Wollastonite Coating Grade Wollastonite Powder Instead of Titanium Dioxide

Wollastonite, also known as siliceous limestone, boasts numerous advantages that make it a highly valuable mineral across various industries.
Firstly, wollastonite fiber is non-toxic, odorless, and non-radioactive, making it an excellent choice for environmentally friendly building materials. It can completely replace asbestos, which is harmful to human health, and partially replace fiberglass, thereby minimizing environmental pollution and reducing production costs.
Secondly, wollastonite exhibits excellent physical and chemical properties, such as high temperature resistance, wear resistance, and corrosion resistance. These properties make it ideal for use in functional coatings, rubber, plastics, friction materials, and other applications where durability and performance are critical.
Furthermore, wollastonite's needle-like physical structure and high whiteness give it advantages in optical and ceramic applications. It can significantly reduce the shrinkage rate of ceramic bodies, lower moisture absorption expansion, and prevent cracking during the later stages of ceramic production
