  • SILICA

     · Silica, such as quartz, is present in most of the earth's minerals. Silica is a hard, glassylike mineral that is found dissolved in water as a result from the bedrock it passes through, like sandstone and granite. In well and surface water, it can range from 1100 parts per million as dissolved (reactive) or undissolved (colloidal) silica. Due to its physical characteristics, silica .

  • Fused Silica for Semiconductor Manufacturing

    One of the first steps in the manufacturing chain of semiconductor devices is the deposition of epitaxial silicon onto the blank silicon wafer. This is done in an epitaxy process. Very often these processes are run with only one wafer being processed at a time ( Single Wafer Processing) or in small numbers ( Multiwafer or Minibatch).

  • Making of fused quartz and fused silica

    Today flame fused quartz is manufactured on a large scale by a continuous process in which highly refined quartz sand is fed through a high temperature flame and deposited on the surface of a melt contained in a tank lined with refractory material. The viscous melt is withdrawn slowly through a die in the bottom of this tank, and it solidifies in a shape determined by the die. In this way it ...
