Precipitated Silica is a form of artificial silica, produced through the process of precipitation of solutions containing silicate compounds.
1.Production process of precipitated silica Precipitated silica is typically created by reacting sodium silicate (Na₂SiO₃) with strong acid (usually sulfuric acid - H₂SO₄) in the aqueous environment
Silica Powder forms as small particles, suspended in water, and then gradually precipitated
2.Characteristics of Precipitated Silica - White powder form. - Large surface area (porous, amorphous) - Insoluble in water and almost organic solvents - Good absorption properties.
3.Applications of precipitated silica - In rubber industry: as a filler to increase durability, and wear resistance. - In pharmaceuticals and food: as anti-caking agent. - In animal feed: as vitamin carrier in premix products - In the printing ink industry: filler, anti-caking, anti-sediment in water-based ink - In glass industry: for borosilicate glass, helps increase melting temperature and glass durability - For ceramics industry: increase heat resistance and durability
