High Purity Quartz Sand

Weden Metal Co.,Limited | Updated: Dec 26, 2017

High purity quartz sand: SiO2 is greater than 99.5-99.9% Fe2O3 is less than 0.005%. It is a natural crystal and natural stone of grade 1-3. It is carefully selected and carefully processed.Particle size range of 1-0.5mm, 0.5-0.1mm, 0.1-0.01 mm, 0.01-0.005mm, can be produced according to the user's requirements. 

High purity quartz sand have unique physical and chemical properties, make its in aviation, aerospace, electronic, mechanical, and today a significant role in the rapid development of IT industry, especially its internal molecular chain structure, the change law of crystal shape and crystal lattice, make its have the high temperature resistant, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect and resonance effect, and its unique optical properties, in many high-tech products plays an increasingly important role.

Purpose: to make glass, refractories, smelting ferrosilicon, metallurgical flux, ceramic and grinding materials, casting, quartz in the building to use its strong acidic medium erosion resistance, used for making acid and acid-resistant cement mortar.As the core raw material of silicon raw materials, quartz sand is an indispensable foundation for the production and supply of silicon raw materials.


The specific application is as follows:

1. glass, flat glass, float glass, glass products, glass jars, glass bottles, glass, etc.), optical glass, glass fiber, glass instruments, conductive glass, glass cloth and the rays, special glass, etc. The main raw material

2. Ceramic and refractory materials: the raw material of porcelain and glaze materials, high silica brick, ordinary silica brick and silicon carbide etc.Metallurgical: raw materials or additives, flux of silicon metal, silicon iron alloy and silicon aluminum alloy

3. Construction: concrete, cementing materials, road materials, artificial marble, cement physical properties inspection materials (cement standard sand), etc

4. Chemical: materials such as silicon compound and water glass, filling of sulfuric acid tower, amorphous silica micropowder

5. Machinery: main raw materials for foundry sand, abrasive materials (sandblasting, hard abrasive paper, sandpaper, emery cloth, etc.)

6. Electron: high purity metal silicon, communication fiber, etc

7. Rubber, plastic: filler (improves wear resistance)

8. Coating: filler (which can improve the weather ability of paint)

9. Metallurgical industry: raw materials or additives, flux of silicon metal, silicon iron alloy and silicon aluminum alloy

10. Aviation, aerospace, its molecular chain structure, crystal shape and crystal lattice, make its have the high temperature resistant, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect, and its unique optical properties.

The production process

1. Ore dressing: sorting the ore

2. Wash mine: clean with naked eye to observe no obvious impurity

3. Calcining: set the oven temperature of 860 degrees centigrade, and the rock shall be red in the discharging time

4. Water quenching: cooling water to quench the structure

5. Crushing: crushed by jaw crusher, then crushed by roller mill

6. Screening: classification of items

7. Cleaning: after many high pure water

8. Water: dehydration through centrifuge

9. Drier: get into the oven and dry

10. Magnetic separation: enter the magnetic separator to remove the iron impurities

11. Enter the flotation machine to select again

12. After manual testing, the packaging is carried out
