Applications

SiO2 (Silicon Dioxide or Silica) in its amorphous form is generally exploited in semiconductors to segregate conducting of differing areas. SiO2 has a high dielectric constant, mechanical resistance, and chemical selectivity. This selectivity makes it a good material in microelectronics and chromatography. Silicon Dioxide has been used in a wide range of applications such as resins for separations, optical fibers, glasses, ceramics, and semiconductors.

Silicon Powder | Low Price $30 | Highly Pure

Silicon Powder | Ultrafine Silicon Powder

Silicon powder is created using the pulverizing method and maintains a very high purity. It has an irregular powder shape and is grey in color. It is not prone to easy oxidation in moist air. We can supply silicon powder with different purity and particle size.

Silicon powder is generally available in most volumes. Nanochemazone produces many standard grades, including military specifications; ACS, Reagent, and Technical Grade; Food, Agricultural, and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) standards. We follow applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety information is available, as is a reference calculator for converting relevant units of measurement.
