   SexCan:Yuan Lei brand quartz powder is a kindWhite amorphous powder, light weight.YLFT"CardQuartzPowderIt is one of the most common and common siliceous mineral raw materials in nature. The main components areSio2, density2.65/cm3The Mohs hardness is7Crystallization is a hexagonal system or block and granular products. Appearance is colorless, white, green gray, etc.

Silica content in98.More than 5 said quartz stone, quartz has a higher refractory performance, melting point of 1730, silicon dioxide content in the following 98.5 said silica.

 

Field of use

Uses: glass and glass products, refractory materials, smelting ferrosilicon, gold flux, ceramics, abrasive materials, casting, cement and products, road marking and chemical industry, lawn sand, etc. Quartz building li has a strong acid and alkali resistance, used to make acid-resistant concrete and acid-resistant mortar, but also to do anti-corrosion coatings, fire prevention, waterproof coatings and so on.

 

Application areas

Use
