According to the "Research on Market Status and Investment Value of China's Wollastonite Industry (2018 Edition)" released by Limu Information Consulting, Wollastonite has a high insulation rate and is a valuable material for the production of functional ceramics. This performance is a valuable material in high-quality power equipment. Wollastonite is used in industries such as radio ceramics, low dielectric loss insulators, ceramic insulation foam for household insulators, and building insulation ceramics. For UHF special electronic instruments, such as high-temperature porcelain components. High-voltage circuit breakers, phenolic bonded resistors, and inorganic insulation materials for manufacturing temperatures above 500 ° C.

 

China's wollastonite mineral reserves are among the best in the world. High-quality deposits of this type include Dadingshan Wollastonite Mine in Lishu County, Jilin Province, Changzhaozi Wollastonite Mine in Panshi County, Jilin Province, Xiaotaipu Wollastonite Mine in Datai, Hubei, Renhe Township, Xinyu City, Jiangxi Province Caofangmiao Wollastonite Mine, Yueguangshan Wollastonite Mine in Shanggao County, Jiangxi Province, Chaotian Wollastonite Mine in Lianzhou City, Guangdong Province, Dulansi Wollastonite Mine in Qinghai Province, Mingguang Baishi Rock Wollastonite in Tengchong County, Yunnan Province Stone mine, Tianshui Houyugou diopside mine in Gansu Province, Jitang Hatang Donggou diopside mine in Ji'an Province, Shandong Pingdu Changle diopside mine, etc. The quality of these deposits is relatively good and the scale is relatively large.

 

Compared with western countries, the current level and scale of wollastonite processing in China is relatively backward. It has a narrow application field and a lower product grade. China's wollastonite products include raw ore ordinary products: 80 mesh, 200 mesh, and 325 mesh, and ultra-fine products of 800 mesh and 1250 mesh. The future direction is mainly to carry out deep (10um) processing of rough-processed products (super Fine crushing and modification) to meet the needs of the development of new materials industry.

 

The development and utilization of wollastonite minerals in China started relatively late. The scale of enterprises is generally small. At present, the development of wollastonite mines in China is mainly concentrated in Jilin, Liaoning, Shandong, Jiangxi, and Guangdong. It is mainly exploited by private and individual enterprises. The resource utilization rate is low. In recent years, under the adjustment of national industrial policies and market mechanisms, it has gradually entered the track of standardized and healthy development, and the production scale, product varieties, and economic benefits of enterprises have been greatly improved. For example, wollastonite companies such as Jilin Lishu and Jiangxi Xinyu have annual output values ​​exceeding the 100 million yuan mark. In short, China has initially formed a resource-based industrial cluster, but the industrial structure is unreasonable, manifested in rough processing products and low proportion of high-tech products; mainly small and medium-sized enterprises, small number of large enterprises, lack of talents, and influence of famous brands Not strong.
