Tosoh Silica Corporation Overview of the Manufacturing

2017-3-22  Overview of the manufacturing process First, a reaction is induced between liquid sodium silica (liquid glass) and sulfuric acid, generating SiO2 and nH2O, in a reaction tank. The reaction conditions are selected to produce silica with different features such as different particle sizes, surface structures, and pore distribution.

Making of fused silica Heraeus

Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica. The achievable maximum content of fluorine in silica is a function of deposition temperature. There is a limit to the maximum fluorine content, because fluorine also etches away fused silica.

The Manufacturing Process The basic process heats silica and coke in a submerged electric arc furnace to high temperatures. High temperatures are required to produce a reaction where the oxygen is removed, leaving behind silicon. This is known as a reduction process. In this process, metal carbides usually form first at the lower temperatures.
