Introduction:

Silicon dioxide is an inorganic compound with the chemical formula of SiO2. The silicon atoms and oxygen atoms are arranged in a long range in order to form crystalline silicon dioxide, and the short range in order or long range in disorder to form amorphous silicon dioxide.

In silicon dioxide crystal, silicon atoms are located at the center of the regular tetrahedron, and four oxygen atoms are located at the four top corners of the regular tetrahedron. Many such tetrahedrons are connected by oxygen atoms at the top corners. Each oxygen atom is shared by two tetrahedrons, that is, each oxygen atom is combined with two silicon protons.

The simplest formula of silicon dioxide is SiO2, but SiO2 does not represent a simple molecule (only represents the ratio of the number of atoms of silicon and oxygen in the silicon dioxide crystal). Pure natural silicon dioxide crystal is a hard, brittle, insoluble, colorless and transparent solid, which is often used for manufacturing optical instruments

Application:

Silica is the raw material for manufacturing glass, quartz glass, water glass, optical fiber, important components of electronic industry, optical instruments, handicrafts and refractories, and is an important material for scientific research.

Silica can also be used as a lubricant and is an excellent flow promoter, especially suitable for granulation of oils and extracts. The particles made have good fluidity and compressibility. It can also be used as a flow aid in direct tablet pressing. As a disintegrant, it can greatly improve particle fluidity and bulk density, and can also be used as a filter aid, clarifier, defoamer, and suspension aid and thickener for liquid preparations
