Production Main Facilities

Quartz has high fire resistance. In industry, quartz sand is often divided into ordinary quartz sand, refined quartz sand, high purity quartz sand, fused quartz sand and silica powder.

1. Ordinary quartz sand

Ordinary quartz sand, i.e. SiO₂ ≥ 90-99%, Fe2O3 ≤ 0.06-0.02%, fire resistance 1750 ℃, appearance: some large particles have yellow capsule on the surface. Ordinary quartz sand is a kind of water treatment filter material which is made of natural quartz ore through crushing, washing, drying and secondary screening. The filter material has the characteristics of no impurities, no edges and corners, high density, high mechanical strength, long pollution carrying capacity line and long service cycle. It is an ideal material for chemical water treatment. The size range is 5-220 mesh, which can be produced according to the user's requirement. Main uses: metallurgy, silicon carbide, glass and glass products, enamel, cast steel, water filtration, foam alkali, chemical industry, spray noise and other industries.

2. Refined quartz sand

Also known as pickling quartz sand, SiO₂ ≥ 99-99.5%, Fe2O3 ≤ 0.005%, using high-quality natural quartz sand, mortar.

3. Glass sand

SiO₂ ≥ 99.5-99.9%, Fe2O3 ≤ 0.001%, using high-quality natural quartz, mortar. (mm is BOM)

4. Fused silica sand

Chemical composition: SiO₂ 99.9-99.95%, Fe2O3 5ppm-25ppm max, li2o1-2ppm max, Al2O3 20-30ppm max

K2O 20-25ppm max, Na2O 10-20ppm max (ppm is one part per million).

5. Physical properties

The appearance is colorless transparent block, particle or white powder.

Relative specific gravity: 2.21.

Mohs hardness: 7.0.

PH value: 6.0.

6. Microsilica

Silica powder: the appearance is gray or gray white powder, and the fire resistance is more than 1600 ℃. Bulk density: 200-250 kg / m3. The chemical composition of silicon powder is shown in the following table:Project SiO_2,Al₂O_3,Fe₂O_3,MgO, CaO, NaO, PH.

7. Average value

75～96%. 1.0±0.2%, 0.9±0.3%, 0.7±0.1%, 0.3±0.1%, 1.3±0.2% Neutral.
