Quartzite
Applications of Quartzite
1. Quartzite can be used as decoration material to manufacture quartz countertops commonly used in household decoration and public buildings.
2. Using advanced crushing equipment and sand making devices in production, we can provide quality quartz grains in multiple specifications that can be classified into .5-1mm, 0.6-1.2mm, 1-2mm, 2-4mm, 8-16mm, and 16-32mm. It is widely used to produce building materials such as the gravel and sand.
3. Quartz sand can also be used to smelt silicon alloys (ferrosilicon, silicon manganese, silicon chromium), serve as flux, or to make glassware.

Characteristics of Quartzite
1. Brittle
2. Pyroelectricity
3. Excellent piezoelectric property
4. Anti-scratch: Quartz levels in our quartzite are as high as 94%, and the hardness of the quartz crystal is 7.5 Mohs, ranked second after diamond, making it resistant to scratches.
5. Environmentally friendly: As it is manufactured under vacuum conditions, this construction material has a compact structure and no pores on the interior or exterior surfaces. Quartzite has a strong corrosion resistance, especially to acid/base products commonly used in kitchens.
6. Durable: The surface of the quartzite has gone through over 30 polishing processes that give it its durability.
7. Fire resistance building material: With a high melting point, quartzite is a typical refractory material.
8. Nontoxic and non-radioactive
