Commercial grade fused quartz is a high purity and high temperature resistant material, commonly used in optical and semiconductor applications. It has a low thermal expansion coefficient and excellent thermal shock resistance, making it ideal for use in extreme temperature environments. Its high purity also makes it resistant to contamination from other materials, which is important in applications such as semiconductor manufacturing. Commercial grade fused quartz is commonly used for lenses, windows, mirrors, and other optical components due to its high optical transmission in the ultraviolet, visible, and near-infrared regions of the spectrum.
