The importance of ceramic raw materials in ceramic production is self-evident. The well-known kaolin used to keep Jingdezhen kilns burning for thousands of years, creating the porcelain capital for thousands of years. However, after a thousand years, the problem of the exhaustion of ceramic raw material resources is like a "tight spell", which has long plagued the development of Jingdezhen's ceramic industry. Microcrystalline fine-grained granite porphyry

After a new type of muscovite granite porphyry ceramic material was found to replace 100% of the traditional porcelain stone, and its production place was in Ehu Town, Fuliang County, it was like "pull the clouds and mist to see the sky". The law. However, this Ehu muscovite porphyry porcelain stone mine is only the beginning for accelerating the development of the ceramic raw material industry. Therefore, the ceramic raw material industry development working group came into being. The municipal government’s leadership will "take command" to investigate and evaluate the ceramic raw material mineral resources in Jingdezhen and its surrounding areas, and strengthen the standardization and serialization of ceramic raw materials. The improvement and technological innovation to realize the scientific development and utilization of ceramic raw materials.

Comprehensive exploration is imperative under the new situation

As a millennium porcelain capital with complete ceramics industry, Jingdezhen has formed three types of ceramic industry systems. The corresponding ceramic raw materials industries are also divided into three types. The first type is daily-use ceramics, artistic ceramics and creative ceramic raw materials, and the source of ore. In the whole country, they are processed into ceramic materials in Jingdezhen; the second category is building ceramic materials, mostly from local materials; the third category is high-tech special ceramic materials, mainly purchased from other places.

"The primary characteristic of traditional Jingdezhen ceramics is that they are white as jade, which refers to the whiteness and blueness, with the warmth like jade, but the current Jingdezhen porcelain part does not reflect this characteristic. I personally think that a large part of this is due to lack of It is the local raw materials that the ancestors depended on for survival, and finally let Jingdezhen go to the world.” said Zhang Mengjin, director of the raw material professional committee of Jingdezhen Ceramics Association and former director of Jingdezhen Ceramic Raw Material General Factory.

At this stage, the existing porcelain stone mines such as Liujiawan in Jingdezhen are almost exhausted. In the face of the new situation of building a national experimental area with all its strength, the prospecting of porcelain stone, especially the exploration of high-quality ordinary porcelain stone minerals, has become a major issue affecting the sustainable development of the porcelain capital. Fortunately, "the effort pays off", the Ehu kaolin mining area adjacent to the famous Kaolin mining area covers an area of ​​9 square kilometers. At least tens of millions of tons of high-quality porcelain stone resources have been proven. According to Jingdezhen Ceramic Porcelain The annual stone consumption is estimated to be 300,000 to 500,000 tons, which can meet the supply of porcelain stone materials for 200 years.

In the fourth issue of the Journal of East China University of Technology (Natural Science Edition) in 2018, a paper entitled "Features of Vein-type Kaolin Deposits in Jingdezhen and Discussion on Prospecting Directions-Taking Ehu Kaolin Mine as an Example" was published. The research pointed out There are still good prospecting prospects in the northeast and southwest extension directions and the southern parallel vein belt outside the Ehu kaolin mining area in the mine field, which enriches people’s understanding of the main industrial types of "kaolin deposits" used in the history of Jingdezhen and their deposit characteristics , Provide backup resource guarantee for Jingdezhen Porcelain Industry.

Therefore, the newly established ceramic raw material industry development working group is divided into a special group for exploration, which is led by the Municipal Natural Resources Planning Bureau. The members are composed of the Provincial Ceramic Industry Company, Leping City, Fuliang County, etc., and are mainly responsible for the investigation of Jingdezhen and its Investigate and evaluate the surrounding ceramic raw material mineral resources to clarify the layout of the ceramic mining industry, the quality of raw materials, and the mineable quantity of the city and the surrounding ceramics.

Enhance R&D and create a new pattern of development

After Jiangxi Ruicai Ceramic Materials Co., Ltd. obtained the right to mine the Ehu kaolin mining area in accordance with the law, Li Yueming, the dean, doctoral tutor, and professor of the School of Materials Science and Engineering of Jingdezhen Ceramics University led the team and joined the technology research and development team for the use of raw ore. . Through a large number of scientific matching experiments, the whiteness of the fired ceramics reaches up to 90%, and the whiteness is blue. In other words, the raw ore produced in the Ehu kaolin mining area can not only replace ordinary porcelain stone for industrial production, but its quality is better than ordinary porcelain stone. Ceramics fired after scientific experimentation

On October 23, 2020, Jingdezhen Ceramics University and Jiangxi Ruicai Ceramic Raw Materials Co., Ltd. jointly developed the scientific and technological achievements of "Production of high-temperature daily-use fine porcelain from Ehu muscovite granite porphyry", which was approved by the China National Light Industry Council. Achievement appraisal meeting. Li Yueming said that the key technology of ore utilization has been overcome, but to truly realize its "gorgeous transformation", it is necessary to work hard on stabilization, standardization, and serialization. At the moment when Jingdezhen is making every effort to build a national ceramic culture inheritance and innovation experimental zone, once the ceramic raw material standards are established, it will further improve the quality of Jingdezhen ceramics, and it will be more conducive to Jingdezhen ceramics to participate in international market competition.

Intensive development to create a characteristic base

To achieve high-quality development of Jingdezhen's ceramic industry, the first thing is to realize the intensive production of ceramic raw materials industry. At present, although there are a few large-scale daily-use ceramic raw materials production enterprises such as Delta, most of them are still small-scale or even family-style raw materials production. A hundred or so raw material workshops are scattered in every corner of the city. Generally, small business scales and loose industrial systems restrict the development of the city's ceramic industry.

In order to achieve the high-quality development needs of Jingdezhen's ceramic industry, the ceramic raw material market needs to be further integrated and jointly improve the ceramic raw material industry level. For this reason, the ceramic raw material industry development working group has also set up a special investment promotion group, which is also led by the Municipal Porcelain Bureau. Its members are composed of the Bureau of Commerce, Fuliang County, High-tech Zone, Changnan New District, etc., and are mainly responsible for introducing national And even the world's advanced ceramic raw materials, glaze enterprises and equipment.

Based on the new development stage, implement the new development concept, integrate into the new development pattern, accelerate the creation of a ceramic raw material production base with Jingdezhen characteristics, and make every effort to promote the development of the ceramic raw material industry to a new level. The ceramic industry is the foundation of Jingdezhen's city, and the ceramic raw material industry is the leader and key of the ceramic industry. It is necessary to effectively play the role of market resource allocation and government policy guidance. It is necessary to increase the introduction of advanced ceramic glaze enterprises and equipment in the country and even the world, serve the high-quality leap-forward development of the ceramic industry, and lay a solid foundation for the construction of the Jingdezhen National Ceramic Culture Inheritance and Innovation Experimental Zone.

In fact, there is still a long way to go for the ceramic raw material industrial chain to meet the high-quality development of Jingdezhen's ceramic industry. However, only by giving full play to the "invisible hand" of the market and the "visible baton" of the government can the Jingdezhen ceramic raw material industrial chain enter the road of intensive development faster, develop into an environmentally friendly and energy-saving industry, and improve the development level of the entire Jingdezhen ceramic industry. .
