Quartz Glass sight glass
Quartz glass, also known as silica glass, plays a vital role in both industry and research. Similar to borosilicate glass, quartz glass has a low coefficient of thermal expansion. Unlike many other technical glasses, it is resistant to only a few acids and can withstand high temperatures of up to 1100°C. Additionally, it exhibits high thermal shock resistance.
Quartz glass is categorized into two types: natural quartz glass and synthetic quartz glass. Synthetic quartz glass (also known as fused quartz glass or fused silica) is produced from pure silicon tetrachloride (SiCl4) through a flame pyrolysis process. On the other hand, natural quartz glass involves grinding rock crystal into powder and melting it using a hydrogen/oxygen flame.
Quartz glass boasts several positive properties, including high temperature resistance, good thermal shock resistance, a low coefficient of thermal expansion, and high purity. Beyond its excellent chemical resistance, quartz glass provides superior light transmission. This makes it a preferred choice for optical applications, offering exceptional optical properties in the ultraviolet, visible, and infrared wavelength ranges. Due to these characteristics, quartz glass is frequently employed in laser applications. It is a commonly used technical glass in many fittings designed for high-temperature applications at ACI.
Properties of Natural and Synthetic Quartz Glass:
Natural quartz glass demonstrates excellent transmission in the UV range, while synthetic quartz glass (fused silica) attains the highest purity through its special manufacturing process. This quartz glass exhibits extremely high purity with minimal inclusions, making it particularly advantageous for optical applications.
ACI provides quartz glass plates in various shapes, including round, rectangular, or oval (tongue-shaped) cuts. We also offer tubes, cylinders, and glass rings.
