Product Description
Wollastonite is a naturally occurring mineral with many unique characteristics.
Through advanced processing, its properties become valuable in a variety of end-use applications. Such as CaO/SiO2=0.93, it has the ideal alkalinity, approaching neutrality. In metallurgical industries, steel madding requires a stable alkalinity. Its alkaline nature also acts as an anti-corrosive agent in paints and coatings. As a raw material source of CaO, it can be used in ceramic glazes and frits. After processing to increase the content of soluble silicon, wollastonite can also be used in agriculture as a compound fertilizer.
One of wollastonite's most unusual characteristics is its needle-like structure. Its high aspect-ratio fibrous particles are very useful in many physical reinforcement applications.
Additionally, the surface treatment of wollastonite leads to superior performance in its use with a variety of organic systems. It permits higher filler loading, improves dispersion, improves powder flow characteristics and so on.
