Silicon Dioxide Powder 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 resigns for separations, optical fibers, glasses, ceramics, and semiconductors.
