Quartzite can be used to manufacture glass, refractory materials, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, casting. Quartzite is used in the building to have strong resistance to acid media erosion, and is used to make acid-resistant concrete and acid-resistant mortar .
As the core raw material of silicon raw material, silicon dioxide plays an irreplaceable and important role in the production and supply of silicon raw material. Its unique physical, chemical and optical characteristics make it play an increasingly important role in many high-tech products, such as the core technology products of the IT industry-computer chips, optical fibers, and resonators in the electronics industry New electric light sources, high-insulation sealing materials, aerospace equipment, military technology products, special optical glass, chemical analysis instruments, etc. are inseparable from these basic raw materials.
