Product Introduction:

Silica is an inorganic substance with a chemical formula of 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 disorderly arranged to form amorphous silicon dioxide.

Under normal conditions, Silicon Dioxide is a transparent or translucent tiny particle with a microporous structure, high mechanical strength, high specific surface area, and high silica content.

It is non-toxic, odorless, and has good thermal stability. It does not react with halogens, hydrogen halides, sulfuric acid, nitric acid, and perchloric acid except fluorine and hydrogen fluoride (except for hot concentrated phosphoric acid).

Silicon oxide is soluble in concentrated caustic soda and has a strong adsorption effect on water vapor and other gases and solvents.

Pure natural silica crystal is a hard, colorless and transparent solid. Because of its unique properties, it is often used in the manufacture of optical instruments.

At present, Silicon Dioxide is divided into different types and is widely used.

Product Types and Usage:

  1. Medicinal Silicon Dioxide: Mainly used as lubricant, anti-sticking agent and glidant.
  2. Silica for food and beverage: glidant, anti-caking performance.
  3. Silicon Dioxide for rubber: It can be used to eliminate internal tension, delamination and cracking in rubber.
  4. Silica for paint coating: control rheology, anti-glare, anti-sagging, anti-ultraviolet, anti-settling, and improve corrosion resistance.
  5. Silicon Dioxide for paper: fast ink absorption, high whiteness, clear and bright printed images.
  6. Silicon Dioxide for molds: excellent dispersibility, compatibility, high transparency, and high light transmittance.
  7. We also produce other silica used in petroleum, edible oil bleaching agent, toothpaste abrasive, leather special matting agent, etc.

Application of Products in Different Fields:

Silicon Dioxide is an important raw material for manufacturing glass, quartz glass, water glass, optical fiber, important parts of the electronics industry, optical instruments, handicrafts and refractory materials.

At the same time, silica is also an important material for scientific research.

When silicon dioxide is completely crystallized, it is a crystal, and after silica gelation and dehydration, it becomes agate, and the hydrous colloid of silicon dioxide becomes opal after solidification.

When the grains of silicon dioxide powder are smaller than a few microns, it forms agate, flint and secondary quartzite.

As a mineral resource with very stable physicochemical properties, crystals belong to trigonal oxide minerals, that is, low-temperature quartz (α-quartz), and are the most widely distributed mineral species in the quartz mineral group.

Quartz in the broad sense also includes high-temperature quartz (β-quartz).

Quartz blocks (also called silica) are mainly used for the production of quartz sand (also called silica sand), and are also raw materials for quartz refractories and ferrosilicon firing.

Silicon dioxide can also be used as a lubricant, and is an excellent flow promoter, primarily as a lubricant, anti-adhesive agent and glidant.

It is particularly suitable for granulation of oils and medicinal extracts, and the manufactured granules have excellent fluidity and compressibility.

It can also be used as a glidant in direct compression.

As a disintegrant, it can greatly improve the fluidity of the particles, increase the bulk density, increase the hardness of the manufactured tablet, shorten the disintegration time limit, and increase the dissolution rate of the drug.

It can be used as an internal desiccant in the manufacture of granules to improve the stability of the drug.

It can also be used as a filter aid for liquid formulations, as a clarifier, as an antifoaming agent, as a suspending agent and as a thickener.
