Industrial Classification of Quartz Sand

Author:Jinlin corundumTo update: 2016-10-14

When you hear quartz sand, you may first think of it is that it can do water purification materials to use, in fact, more than quartz sand can do water purification materials, which can also be used as abrasive. In order to facilitate the majority of users can more quickly find their own products, the following is my company for the industrial classification of quartz sand made a brief introduction.
Before we understand the industrial classification of quartz sand, we need a basic understanding of quartz sand. Quartz sand is a hard, wear-resistant, chemical stability of silicate minerals, the main mineral composition is SiO2, quartz sand color is milky white, or colorless translucent, hardness of 7, the density of 2.65, the chemical , Thermal and mechanical properties of a significant anisotropy, insoluble in acid, slightly soluble in KOH solution, the melting point of 1750 ℃.
With the same brown fused alumina, quartz sand has a high fire resistance, industrial quartz sand is often divided into: ordinary quartz sand, refined quartz sand, high purity quartz sand, fused silica sand and silicon powder.
1. Ordinary quartz sand
Ordinary quartz sand SiO2 ≥ 90-99%, Fe2O3 ≤ 0.06-0.02%, refractoriness of 1750 ℃, the appearance of some large particles, the surface of yellow cysts. Ordinary quartz sand is generally used in natural quartz ore, broken, washed, dried, the second screening made.
Ordinary quartz sand Main purposes: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, soda, chemical, spray noise and other industries.

2. Refined quartz sand
Refined quartz sand, also known as pickling quartz sand, SiO2 ≥ 99-99.5%, Fe2O3 ≤ 0.005%, the use of high-quality natural quartz stone, mortar.
3. High-purity quartz sand
High-purity quartz sand SiO2 ≥ 99.5-99.9%, Fe2O3 ≤ 0.001%, using high-quality natural quartz stone, mortar.
4. Fused silica sand
The chemical composition of the fused silica sand is SiO2: 99.9-99.95%; Fe2O3: 5PPM-25PPMmax; Li2O: 1-2PPMmax; Al2O3: 20-30PPMmax; K2O: 20-25PPMmax; Na2O: 10-20PPMmax. (PPM is one millionth unit)
Fused silica sand physical properties: appearance is colorless and transparent lumps, particles or white powder, relative specific gravity: 2.21; mohs hardness: 7.0; PH value: 6.0.
5. Microsilica
Silica powder: the appearance of gray or off-white powder, refractoriness> 1600 ℃, bulk density: 200 ~ 250 kg / cubic meter.
Shizui Mountain Jinlin Fused Alumina Refractories Co., Ltd. is a diversified production plant, set the development, production, sales and service in one. The company mainly produces fused alumina products, brown fused alumina, white fused alumina, silicon carbide, bauxite, alumina ball, garnet, alumina powder, zircon sand, castable and other products specializing in the production and processing company, with a complete and scientific quality management system.
These are my company for the industrial classification of quartz sand made by a brief description, I hope you can help. Thank you for reading, please continue to pay attention to our website!
