Application of silica solution

Silica solution is achromatic clear-cut or white glue. Soluble in hydrofluoric acerbic and sodium hydroxide solution, baffling in baptize and added asleep acids. Uses for accurate industry. Binder system. Precision casting. Long-wave bittersweet radiation paint. Crystals of silica, silicon atoms of 4 valence electrons and 4 oxygen atoms anatomy 4 covalent bonds, Hara Ko is amid in the centermost of the tetrahedron, 4 oxygen atoms are amid in the 4 corners of the tetrahedron, SiO is bidding constitutively in the simplest form, is alone said silica crystals of silicon and oxygen atoms ratio. Silica is the diminutive crystal. Actinic backdrop of almost stable. Baffling in baptize nor with baptize reaction. Is acerb oxide, not with the accustomed acerbic reaction. Aerial hydrogen fluoride reacts with the silicon dioxide aerial four silicon fluoride. With hot concentrated acrid band-aid or the acknowledgment of aqueous acrid silicate and water. With a array of metal oxides at top temperature acknowledgment of silicate. Acclimated in the accomplish of quartz glass, optical instruments, actinic containers, glass, refractories, optical fiber, ceramics etc.. The attributes of the silica is not lively, it is not with fluorine, hydrogen fluoride, hydrogen halide and added halogen acid, nitric acid, perchloric acerbic aftereffect ( hot concentrated phosphoric acerbic with the exception).

Silica solution is the accomplish of glass, quartz glass, baptize glass, optical fiber, key apparatus of the electronics industry, optical instruments, crafts and adverse raw materials, accurate analysis is the important material. When the time is absolute apparent silica crystal; silica gel afterwards aridity is agate; alliance colloidal silica baptize afterwards a opal; silica atom is beneath than several micrometers, on the accumulation of chalcedony, flint, accessory quartzite. Physical and actinic backdrop are actual abiding mineral resources, the clear belongs to three affair arrangement oxide minerals, namely low quartz ( a- quartz, quartz minerals ) is the a lot of broadly broadcast as a mineral species. Generalized quartz aswell includes temperature quartz ( b- quartz ). Quartz block, aswell accepted as silica, mainly the assembly of quartz beach ( aswell accepted as silica beach and quartz ) raw materials, refractories and battlefront ferrosilicon raw materials. In the aliment industry is mainly acclimated to anticipate arenaceous aliment clumps, to advance the chargeless breeze of a affectionate of aliment additives or acclimated for adsorption of aqueous spices, oils, vitamins and so on, accomplish the powder, such as delicate oil, solid aroma and solid beverages such products.
