Quartz Product Introduction

Quartz is the main mineral component of silica ore. Contains 46.70 percent silicon. There are trigonal low-temperature quartz (α-quartz) and hexagonal high-temperature quartz (β-quartz). Quartz is generally referred to as low-temperature quartz. Trigonal crystal system, the crystal is hexagonal columnar, and twin crystals are common. Usually in the form of crystal clusters, materials, and massive aggregates. It is in various colors, colorless and transparent are called crystal, milky white is called milk quartz, purple is called amethyst, light rose is called rose quartz, smokey is called smoky quartz, brown is called citrine, etc. . [2] Vitreous luster. Hardness 7, density 2.65g/cm3. Insoluble in any acid except hydrofluoric acid. Mineral components of various rocks and deposits. Used in the manufacture of silica gel, water glass and various silicides and silicates, used as fillers for plastics and rubber. It is also widely used in glass, ceramics, petroleum, metallurgy, casting, building materials and other departments.

Purity is an important indicator of quartz glass, which has a great influence on physical and chemical properties and performance, such as devitrification, high temperature strength, softening point, light transmission, thermal stability, chemical stability, radiation resistance, fluorescence characteristics, etc.; in addition , Quartz glass used in the semiconductor industry has more stringent requirements on purity, and trace impurities will have a serious impact on the electrical properties, life and integration of semiconductor materials. Since the purity of semiconductor materials is required to be controlled below the ppb level, the quartz glass should be controlled at the ppm level to meet the needs of the semiconductor industry. The segregation coefficient of B is close to 1, Cu, Fe, Ti, etc. affect the minority carrier lifetime of semiconductors, and K, Na, Li are harmful impurities that produce micro-defects in single crystal materials.

Quartz glass has high dielectric strength and relatively low conductivity, that is, it can still maintain high dielectric strength and resistance under high temperature, high pressure and high frequency, and has almost no dielectric strength in the applied frequency band. loss, so quartz glass is an excellent high-temperature dielectric insulating material. At room temperature, its resistance is equivalent to 10 times that of ordinary glass, the dielectric loss for all frequencies is very small, and the dielectric strength is high.

Our company is mainly engaged in quartz finishing, quartz instruments, Alfa looks forward to reaching long-term cooperation with customers.
