- High Purity: It is a high-purity material that is free from impurities and contaminants.
- High Hardness: It is a hard material that has a Mohs hardness of 7, making it ideal for use in abrasive applications.
- High Heat Resistance: It is a material that has high heat resistance and can withstand temperatures of up to 1650°C.
Applications of Silica Powder
- Abrasives: It is used as an abrasive material in various applications such as sandblasting, polishing, and grinding.
- Glass: It is a key ingredient in the production of glass, where it is used as a fluxing agent to lower the melting point of the glass.
- Ceramics: It is used in the production of ceramics such as porcelain and ceramic tiles. It is used as a filler and a binder in the ceramic mixture to improve the strength and hardness of the finished product.
- Paints and Coatings: It is used in the production of paints and coatings as a filler and a rheological modifier. It improves the flow and the durability of the finished product.
- Playing Colours: Due to its lightness and inertness, this material is most widely used for making Holi and Rangoli colours.
