Quartz is a hard, crystalline mineral composed of silicon dioxide (SiOâ??). It is one of the most abundant and versatile minerals on Earth, known for its durability, clarity, and resistance to weathering. In industry, quartz is primarily used in the production of glass, ceramics, and as a raw material for silicon in electronics. Its piezoelectric properties make it essential in the manufacturing of precision instruments, such as watches and oscillators, where it is used to maintain accurate timekeeping and frequency control.
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO·2HO). It is widely recognized for its versatility and is commonly found in sedimentary rock formations. The primary use of gypsum is in the construction industry, where it is a key ingredient in the production of plaster, drywall (also known as gypsum board or sheetrock), and cement. Gypsum's ability to harden when mixed with water makes it ideal for creating smooth wall finishes, ceiling tiles, and as a fire-resistant barrier in building materials. Additionally, it is used in agriculture as a soil conditioner to improve soil structure and nutrient availability.
