Quartz sand
The quartz sand is one kind hard, is wear-resisting, chemistry performance stable silicate mineral, its essential mineral ingredient is SiO2, the quartz sand color for the cream color or the colorless translucent shape, degree of hardness 7, the nature crisp not cleaves, the conchoidal fracture, the oily luster, the relative density is 2.65, its chemistry, the heat studies and the machine capability have obviously, does not dissolve to the acid, The colorless transparent crystal is called the quartz, moreover also has includes the impurity but to bring the color (to contain manganese), the smoke-stone (contains organic matter), the
The quartz sand has the unique physics, the chemical characteristic, enable it in the IT industry which the aviation, astronautics, the electron, the machinery as well as now rapidly develops to hold the pivotal status, specially among them in the molecular chain structure, the crystal shape and the crystal lattice change rule, enable it to have thermostable, the thermal-expansion coefficient small, highly insulates, is anti-corrosive, the piezoelectric effect, the resonance effect by and its the unique optics characteristic, is playing the more and more vital role in many high tech products.
Use: The manufacture glass, the fire-proof material, the smelting ferrosilicon, the metallurgy melting agent, the ceramics, grind the material, the casting, the quartz use it in the construction to have the very strong acid resisting medium ability, uses for the system to take the acid-resisting concrete and the acidproof mortar. The quartz sand took the silicon raw material the core raw material the important foundation function which cannot be substituted in the silicon raw material production and the supply. In addition the quartz sand also widely applies to the radar, the navigation, the remote control, the electron, the telecommunication equipment aspect.
The quartz sand main specification includes: 6 - 8 mm, 4 - 6 mm, 10 - 20 item, 20 - 40 item, 40 - 80 item, 80 - 120 item, 200 item, 325 item, 1,000 item and so on.
