What is the nature and use of quartz sand and quartz sand?

What is quartz sand?

  1. Quartz is called silica if the content of silica is above 98.5%, and silica is called when the content of silica is below 98.5%.
  2. Quartz stone is called quartz sand after crushing. Quartz sand is divided into refined, semi-refined and ordinary.
  3. Characteristics: Quartz has a hardness of 7, with a specific gravity of 2.65, and its color is milky white, light yellow, brown, and gray. Quartz has high fire resistance and a melting point of 1730 degrees Celsius.
  4. Uses: manufacturing glass, refractory materials, smelting ferrosilicon, metallurgical fluxes, ceramics, abrasive materials, casting, using the strong acid resistance of quartz in the building to etch acid, used to make acid-resistant concrete and acid-resistant mortar.
  5. silica as the core raw material of silicon raw materials plays an irreplaceable and important role in the production and supply of silicon raw materials. Its unique physical and chemical characteristics make it occupy a pivotal position in aviation, aerospace, electronics, machinery and today’s rapidly developing IT industry, especially its internal molecular chain structure, crystal shape and lattice change law, Its high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics make it play an increasingly important role in many high-tech products, such as IT The core technical products of the industry-computer chips, optical fibers, resonators in the electronics industry, new electric light sources, high-insulation sealing materials, aerospace instruments, military technology products, special optical glass, chemical analysis instruments, etc. These basic raw materials cannot be opened.

The nature and use of quartz sand

Quartz sand is divided into two types, refined and common: the hardness of quartz is 7, the specific gravity is 2.65, the color is milky white, light yellow, brown and gray. Quartz has high refractory performance. Fluxes, ceramics, abrasive materials, casting, use of quartz’s strong resistance to acid medium erosion in construction, used to make acid-resistant concrete and acid-resistant mortar. Especially used as water treatment filter material, high strength, strong interception ability, good acid resistance. It is also the main raw material for industries such as glass, ceramics, enamel, thermo bottles, sodium silicate, casting, building materials, grinding, refractory, military industry, and communications.
