Wollastonite is a naturally occurring mineral known for its unique properties and wide range of applications. It is a calcium inosilicate mineral (CaSiO3) that typically occurs in metamorphic rocks. Wollastonite forms when limestone or other high-calcium rocks undergo high temperature and pressure conditions, often in the presence of silica.
Brightness and Whiteness: Wollastonite has a naturally high brightness and whiteness, making it an excellent pigment and filler in various applications.
Low Moisture and Oil Absorption: This property makes it useful in coatings and polymers, where control over moisture and oil levels is crucial.
Chemical Stability: Wollastonite is stable in both acidic and basic environments, enhancing its utility in diverse chemical applications.
Low Volatile Content: Ensures minimal outgassing in high-temperature applications.
