Industry insiders are well aware that although fused silica micro powder is a processed product of quartz sand, the differences between the two are quite apparent. Below, we will separately introduce the characteristics of fused silica micro powder and quartz sand to share with you.
Fused Silicon Micro Powder is a micronized material produced through a series of processes, including crushing, ball milling (or vibration, air jet milling), flotation, acid washing, and high-purity water treatment. It is derived from natural quartz (SiO2) or fused quartz (non-crystalline SiO2 obtained from melted and cooled natural quartz).
Natural quartz ore, due to its large size, is not easily processed into silicon micro-powder. Therefore, it must be fractured and graded into quartz sand, which is then processed into silicon micro-powder.
What is the difference between fused silicon micro powder and quartz sand?
1. Quartz sand comes in a milky white or colorless semi-transparent form, with a hardness of 7. As a primary industrial raw material, quartz sand is non-hazardous and is widely used in water purification, glass manufacturing, casting, ceramics, refractory insulation materials, silicon iron smelting, metallurgical fluxes, metallurgy, construction, chemical industry, plastics, rubber, abrasives, and other industries. Particularly in the water purification industry, quartz sand filter media is a commonly used, high-dosage water treatment material.
2. Silicon micro powder is a non-toxic, odorless, green and environmentally friendly inorganic non-metallic material. Due to its excellent temperature resistance, resistance to corrosion and embrittlement, poor thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in industries such as chemical, electronics, integrated circuits (IC), electrical appliances, plastics, coatings, high-grade paints, and rubber.
