Silica is a chemical compound commonly used in paper coating, especially in matte papers used in ink-jet . The silica-gel properties are very particular, namely high surface area, hydrophilicity, and internal porosity, allowing easy ink diffusion along the coating layer. Moreover, silica improves the brightness and opacity of paper.

In hot rolling mills, descaling equipment ensures high surface quality. During descaling, the material surfaces are sprayed with water under high pressure to blast off and completely remove the scale. The working pressure can be up to 450 bar, depending on the size of the plant. Water volumes between 200 and 700 m³ per hour are used.

15.The initial step is extraction of silica from ash as sodium silicate using caustic soda. This reaction is carried out at a temperature in the range 180ºC-200ºC and pressure ranging from 6-8 atmospheres. But high reaction temperature and pressure can be avoided if ash obtained by burning rice husk at 650ºC is used.
