Our technology advantage

Our technology advantage

We could design and build 1000~10000t/a fumed silica production line.
We use advanced feeding process, flame control process and aggregation control process, which can control particle formation to obtain the ideal size.
We are able to control the number of hydroxyl groups on the aggregate surface during the process, for achieving the ideal viscosity.

Introduction of Fumed silica

Fumed silica is an important nano-inorganic chemical material. It has a small particle size (7-40nm), a large specific surface area (50-400m2/g), and a high product purity (SiO2≥99.9%) . The product has excellent surface chemical properties and good physiological inertia. It has a wide range of applications in the fields of silicone rubber, adhesives, paints, coatings, inks, electronics, paper, cosmetics, medicine, food, and agriculture. Thickening, thixotropy, extinction and other functions are indispensable raw materials and additives in the national basic people's livelihood industry, national defense industry, and high-tech fields.

Raw material and reaction equation

The raw materials for fumed silica production are mainly chlorosilane, hydrogen, and air. Among them, chlorosilanes mainly include silicon tetrachloride, trichlorosilane, monomethyltrichlorosilane, dichloromethylsilane, etc.

Silicon tetrachloride: SiCl4+ 2H2+ O2 → SiO2 + 4HCL

Trichlorosilane: SIHCL3 +1.5H2 + O2 → SiO2 + 3HCL

Monomethyltrichlorosilane: CH3SICL3 +2H2+ 3O2 → SiO2 + 3HCL + 2H2O + CO2

Dichloromethylsilane (one methyl contains hydrogen): CH3HSiCL2 + H2+ 3O2→ SiO2 +2HCL +2H2O + CO2
