Quartz is a crystalline form of silicon dioxide (SiO2) and is one of the most abundant minerals on Earth. It is found in various geological environments and comes in different varieties and colors, including clear, white, rose, and smoky quartz. Quartz crystals have a hexagonal crystal structure and often exhibit well-defined faces and edges.
Here are some key details about quartz:
- Chemical Composition: SiO2 (Silicon Dioxide)
- Crystal System: Hexagonal
- Hardness: 7 on the Mohs scale, making it relatively hard.
- Transparency: Transparent to translucent
- Luster: Vitreous (glass-like)
- Specific Gravity: 2.65
Uses in Industrial Applications:
- Glass Manufacturing: Quartz is a crucial raw material in the production of glass. Its high melting point and thermal stability make it an ideal component for glass formulations. It is used in the manufacturing of glass containers, fiberglass, and other glass products.
