| Applications : |
| Paint and Coatings: Paint formulators select micron-sized industrial sands to improve the appearance and durability of architectural and industrial paint and coatings. High purity silica contributes critical performance properties such as brightness and reflectance, colour consistency, and oil absorption. Glass making: Silica sand is the primary component of all types of standard and specialty glass. It provides the essential SiO2 component of glass formulation, and its chemical purity is the primary determinant of colour, clarity, and strength. Metal Casting: Industrial sand is an essential part of the ferrous and non-ferrous foundry industry. Metal parts ranging from engine blocks to sink faucets are cast in a sand and clay mold to produce the external shape, with a resin bonded core creating the desired internal shape. Metal Production: In metal production, silica sand operates as a flux to lower the melting point and viscosity of the slags to make them more reactive and efficient. Chemical Production:Silicon-based chemicals are the foundation of thousands of everyday applications ranging from food processing to toothpaste, the silica is widely used in many areas. |
