Product Description
Usage
Fumed silica is a basic functional product used in construction, automobile, semiconductors, etc. It acts as a function reinforcement agent, and it can also optimize a product by improving anti-sagging and anti-settling effects or abrasive properties. The fumed silica business continues to advance alongside the growth of mobile phone, kitchenware, cosmetics, construction, automobile, semiconductors, shipbuilding, etc.
Silicone Chain
Silicone is produced through the chemical synthesis of mineral silicon (SiO2), and it is transformed and used as a high-functioning, high-quality precision material in various fields from industrial goods to daily supplies. With the advancement of technology, silicone will continue to be developed as a material supporting next-generation technologies.
Production Process
Fumed Silica is synthesized from the hydrolysis of high purity silane in a flame of oxygen and hydrogen at temperature over 1000℃. The raw material, silane, synthesized through a reaction of metallurgical silicon, which is obtained through a reduction of mineral silicon dioxide (SiO2) with cokes, and hydrogen chloride.
