Ceramic-grade wollastonite powder adding an appropriate amount of wollastonite powder to the ceramic raw materials can greatly reduce the firing temperature, shorten the firing time, and achieve rapid firing at low temperature. It saves a lot of fuel and obviously reduces the cost of the product; at the same time, it improves the mechanical properties of the product, reduces the cracks and warpage of the product, increases the glaze gloss, and improves the strength of the embryo body, thereby increasing the qualification rate of the product.
