Micronized Silica

When acid is added to sodium silicate, silica sol with primary particle is created.Radical dehydration condensation reaction is promoted at silano(Si-OH) on the surface of primary particle by continuous adding of acid. As a result, network (Si-O-Si) is formed and three dimensional structure is generated. This is so called Silica gel. Physical properties are controlled via washing and drying processes and finally Micronized silica is produced by grinding it.Micronized silica has various special propertie by porosity and paricle size distribution,and it is applied widely in various fields using the characteristics.
