Product Description

Product Description

         
             Silicon dioxide is an inorganic compound with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in long-range order to form crystalline silica, and short-range order or long-range disorder are arranged to form amorphous silica. In the silicon dioxide crystal, the silicon atom is located in the center of the regular tetrahedron, and the four oxygen atoms are located at the four vertex corners of the regular tetrahedron. Many such tetrahedrons are connected through the oxygen atoms at the vertex corners. Each oxygen atom is Two tetrahedra are common, that is, each oxygen atom is bonded to two silicon atoms. Pure natural silica crystal is a hard, brittle, insoluble, colorless and transparent solid, often used in the manufacture of optical instruments, etc.

 

Product Parameters

           Silica is a raw material for manufacturing glass, quartz glass, water glass, optical fiber, important components of the electronic industry, optical instruments, handicrafts and refractory materials. It is an important material for scientific research. Silica is mainly a raw material for the production of quartz sand (also known as silica sand), as well as a raw material for quartz refractory materials and fired ferrosilicon. In addition, silica can also be used as a lubricant and an excellent flow promoter, mainly used as a lubricant, anti-sticking agent and flow aid. It is especially suitable for granulating oils . The granules produced have good fluidity and compressibility. It can also be used as a filter aid, clarifying agent, defoaming agent, as well as a suspending agent and thickener for liquid preparations
