Introduction / 产品简介

Product introduction 产品介绍

Quartz has high refractory performance. In industry, quartz sand is often divided into: ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand and silicon powder.
1. Ordinary quartz sand: SiO2≥90-99% Fe2O3≤0.06-0.02%, refractoriness 1750 ℃, large particles in appearance, and yellow skin encapsulation on the surface. The granularity range is 5 to 220 mesh, which can be produced according to user requirements. Main uses: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, caustic soda, chemical, spray and other industries.
2. Refined quartz sand: SiO2≥99-99.5% Fe2O3≤0.02-0.015%, selected and processed by high-quality ore.
The particle size range is 5-480 mesh, which can be produced according to user requirements. The appearance is white or crystalline. Main uses: high-grade glass, glass products, refractory materials, smelting stones, precision casting, grinding wheels, etc.
3. High-purity quartz sand: SiO2≥99.5-99.9% Fe2O3≤0.005%, which is made of 1-3 grade natural crystal stones and high-quality natural stones, which are carefully selected and finely processed. Granularity range 1—0.5mm, 0.5—0.1mm, 0.1—0.01mm, 0.01—0.005mm, can be produced according to user requirements. (mm is Bom)
Fourth, fused silica sand: chemical composition:
SiO2 99.9-99.95% Fe2O3 5PPM-25PPM max Li2O 1-2PPM max Al2O3 20-30PPM max
K2O 20-25PPM max Na2O 10-20PPM max (PPM is one millionth unit)
Physical properties:
Appearance is colorless transparent block, granules or white powder.
Relative specific gravity: 2.21;
Mohs hardness: 7.0;
PH value: 6.0;
Fifth, silicon powder
Silica micropowder: Appearance is gray or off-white powder, refractoriness> 1600 ℃. Density: 200 ~ 250 kg / m3. The chemical composition of silicon micropowder is shown in the table below:
Project SiO2 Al2O3 Fe2O3 MgO CaO NaO PH
verage 75 ~ 96% 1.0 ± 0.2% 0.9 ± 0.3% 0.7 ± 0.1% 0.3 ± 0.1% 1.3 ± 0.2% Neutral
Quartz is a stable mineral at room temperature, insoluble in water and sulfuric acid, hydrochloric acid, nitric acid. Hardness 7, specific gravity about 2.65, melting point 1713 ℃. The gloss is glassy, ​​sometimes fat. Those with pure texture are colorless; those with impurities include red, yellow, blue, black, brown, purple, and green; transparent to opaque, and brittle. The fracture is shell-shaped or uneven. The crystal is in the shape of a hexagonal column, and the column mask has horizontal stripes. There is a difference between left crystal and right crystal. Twin crystals are common. Usually clusters or granular, massive aggregates. Quartz has the ability to transmit ultra-ultraviolet rays and is not conductive. Quartz undergoes homogeneous deformation during uniform heating or cooling, and maintains its own symmetry before being transformed into another polymorphic variant. Quartz crystal has the optical properties of birefringence and rotating polarized surface, and has piezoelectric effect. The oscillation frequency of the quartz plate has a high degree of stability, and the ultrasonic energy is radiated using the oscillation energy of the quartz plate.
