Quartz Glass Crucible Descriptions
Quartz Glass Crucible is made of fused silica. Quartz glass is an amorphous material with a single component of silicon dioxide, and its microstructure is a simple network composed of four structure units of silicon dioxide. Due to the large si-O chemical bond energy and tight structure, quartz glass has unique properties, especially excellent optical properties of transparent quartz glass.
