Acidic oxides large companies can directly generate acid silica compound with water, but did not directly SiO2 compound with water. Its corresponding hydrate - silicate, only the reaction with the corresponding acid was obtained with a soluble silicate (silicate insoluble in water, is a weak acid, it is even weaker than carbonic acid). Acidic oxides generally not with the action of acid, but the SiO2 was sorted hydrofluoric acid reacts silica products, generated gaseous silicon tetrafluoride. SiO2 + 4HF == SiF4 ↑ + 2H2O ordinary glass, quartz glass main component is silica. Hydrofluoric acid, which can be used to etch glass. Hydrofluoric acid carved lettering on the glass, the laboratory can not use hydrofluoric acid silica-containing glass, ceramics, porcelain, pottery bloom, usually available in plastic bottles. SiO2 and alkali water glass solution reaction can generate, it is a good sales Which mineral silica gel, used as a binder. So laboratory reagent bottle full bloom alkaline solution without glass stopper, and with a rubber stopper. Silica structure. "" "The use of silica silica is widely used, the main raw material has been used in high-performance fiber-optic communications material is silica. Generally more pure quartz glass used to manufacture quartz. Quartz glass used in the manufacture of high temperature chemical instruments. Crystal used to manufacture key components of the electronics industry, optical instruments, also used to make high-level industrial and glasses tablets. Fumed silica can greatly improve the physical and mechanical properties of rubber, plastic material to reduce lag, reduce the rolling resistance of the tire without loss of wet skid resistance and attracted widespread attention, so the application of other organic rubber silicone rubber outside the more widely, its reinforcing effect fully reached the level of carbon black, carbon black and because overcome pollution, can be widely used in high-end color rubber products.
