Silicon dioxide is an inorganic compound with the chemical formula SiO2. Silicon atoms and oxygen atoms are arranged in a long-range order to form crystalline silicon dioxide, and short-range order or long-range disordered arrangement to form amorphous silicon dioxide.
In a silicon dioxide crystal, the silicon atom is located in the center of the regular tetrahedron, and the four oxygen atoms are located on the four top angles of the regular tetrahedron, and many such tetrahedrons are connected by the oxygen atoms of the top angles, each oxygen atom is shared by the two tetrahedrons, that is, each oxygen atom is combined with two silicon atoms.
The simplest form of silicon dioxide is SiO2, but it does not represent a simple molecule (only the ratio of the number of atoms of silicon and oxygen in the silicon dioxide crystal).
Pure natural silica crystal, is a hard, brittle, insoluble colorless transparent solid, often used in the manufacture of optical instruments.Silicon dioxide is the manufacturing of glass, quartz glass, water glass, optical fiber, electronic industry important components, optical instruments, crafts and refractory materials, is an important material for scientific research.
When silica crystallization is crystal, after gelatinization and dehydration is agate, the aqueous colloid solidified to become opal, silica grains less than a few microns, it is composed of chalchalith, chert, secondary quartzite.
Physical and chemical properties are very stable mineral resources, crystal tripartite oxide minerals, namely low-temperature quartz (α-quartz), is the most widely distributed mineral species in the quartz group minerals.
The broad definition of quartz also includes high-temperature quartz (β-quartz). Quartz block, also known as silica, is mainly the raw material for the production of quartz sand (also known as silica sand), and is also the raw material for quartz refractory and fired ferrosilicon.
In addition, silica can also be used as a lubricant, is an excellent flow accelerator, mainly as a lubricant, anti-viscosity agent, flow aid.
It is especially suitable for the granulation of oil and extract drugs, and the particles produced have good fluidity and compressibility. It can also be used as a flow aid in direct compression tablets.
As a disintegrator, it can greatly improve the particle fluidity, increase the bulk density, increase the hardness of the prepared tablets, shorten the disintegration time and increase the dissolution speed.
The granule can be used as internal desiccant to enhance the stability of the drug. It can also be used as filter aid, clarifying agent, defoamer and suspension aid and thickening agent of liquid preparation
