* Paints and Coatings: Used as a component of white pigment, as a transparent filler that prevents flocculation of colored pigments or to modify consistency. It acts as a spacer for TiO2 or white pigment, improving the TiO2 efficiency and lower productiong cost.
* Paper: Used as a brightener and extender.
* Plastics: Used as a filler to make transparent filler masterbatch and white masterbatch. Used to improve the plasticity of plastics.
* Rubber: Used to improve scratch resistance of polyolefins.
* Battery: In lead-acid batteries (e.g. car batteries), it acts as a seed crystal for the lead-to-lead sulfate reaction.
