Molten Quartz Blocks

We use high-purity quartz sand from our company as the raw material, which is converted into amorphous silicon dioxide through high-temperature melting (electric melting temperature of 1800-2000°C). According to different applications, it is graded into block form (外观无色透明, with a small amount of fibrous matter). Melted quartz has a very low coefficient of thermal expansion and thermal conductivity, excellent thermal stability, and stable chemical properties. It is processed through special machinery, including decontamination, crushing, screening, and magnetic separation, and is widely used in industries such as photovoltaics, large-scale integrated circuits, epoxy resin casting, high-grade refractories, technical ceramics, and precision casting.

Primary Application:

Electronic sealing material, epoxy resin casting material

Cast Materials

Fireretardant, ceramic, and glass industry raw materials
