Chemical properties folded relatively chemically stable. Insoluble in water nor react with water. Acidic oxides, not with the general acid. Gaseous hydrogen fluoride is reacted with silica to form gaseous silicon tetrafluoride. Concentrated alkali solution with hot or molten alkali silicate and water reaction. With more metal oxides at high temperature produced by the reaction of silicate. For the manufacture of quartz glass, optical instruments, chemical containers, ordinary glass, refractory materials, optical fiber, ceramics and the like. The inert nature of the silica, it does not fluorine, halogen other than hydrogen fluoride, hydrogen halides and sulfuric acid, nitric acid, perchloric action (except hot concentrated phosphoric acid). Common concentrated phosphoric acid (or pyrophosphate) under high temperature corrosion of silica to produce the heteropolyacid [2], molten borate or boric anhydride may silica silica credibility high temperature corrosion, in view of this Silica Company nature, borate can be used for good quality flux Which ceramic firing of the silica, in addition to hydrogen fluoride can be dissolved silica acid, soluble in water to generate fluorine silicate: SiO + 4HF = SiF4 ↑ + 2H O silica is manufactured glass, quartz glass, water glass, optical fiber and refractory materials??. When the time is perfect crystalline silica crystal; after silica gel of dehydration is agate; colloidal silica water after solidification become opal; silica grains at less than a few microns, on the formation of chalcedony, chert, secondary quartzite. Which is cheaper silicon dioxide, silicon dioxide, Weifang Fuyuan provided by Weifang Fuyuan Environmental Technology Limited. Weifang Fuyuan Environmental Protection Technology Co., Ltd.
