Application of wollastonite in metallurgical industry
Wollastonite plays a crucial role in the metallurgical industry. Its unique physicochemical properties, such as high silicon content, low iron content, and good heat resistance and chemical stability, make it an ideal additive in metallurgical processes.

The function of wollastonite in ceramic glaze
Wollastonite can significantly improve the gloss, smoothness and adhesion of the glaze surface, while reducing the glaze defects (such as pinholes, cracks). Studies have shown that adding 5% -10% wollastonite powder to the glaze can increase the glaze gloss by 10% -15% and reduce the glaze defect rate by 30% -40%.
The production process of wollastonite
The first step: mining, the wollastonite ore is mined from the mine through tunneling, and then transported to the processing plant. During the mining process, attention needs to be paid to protecting the environment and avoiding pollution to the surrounding ecological environment.
Wollastonite composition content
硅灰石的主要成分是偏硅酸钙(CaSiO₃),其化学式为Ca₃Si₃O₉,其中氧化钙(CaO)占43%左右,二氧化硅(SiO₂)占52%左右。
What are the advantages of industrial application of wollastonite tailings?
Efficient utilization of resources: The industrial application of wollastonite tailings helps to achieve efficient utilization of resources and reduce resource waste. Transforming tailings into valuable products through technical means improves the utilization rate of resources
