High purity synthetic quartz glass has emerged as a vital material in various cuttingedge applications, distinguishing itself through its remarkable properties and attributes. This article aims to shed light on the working principle and diverse applications of this extraordinary material while taking a gentle approach to the complexities involved.
Working Principle
High purity synthetic quartz glass is engineered through a meticulous process that ensures the elimination of impurities, resulting in a substance that boasts exceptional clarity and chemical resistance. This is accomplished through a technique known as the hydrolysis of silicon tetrachloride (SiCl4), which is a precursor for the synthesis of high purity silica.
The process begins with the controlled reaction of silicon tetrachloride with water, leading to the formation of fine silicon dioxide (SiO2) particles. These nanoparticles are then aggregated and consolidated through a hightemperature fusion process, where they are heated to temperatures exceeding 1,600 degrees Celsius. This step not only removes residual water but also facilitates the formation of a dense and homogeneous silica network.
The result is synthetic quartz glass that exhibits a unique combination of properties. Its high thermal stability allows it to withstand extreme temperatures, while its low thermal expansion ensures minimal distortion or cracking. The measured refractive index contributes to its transparency across a range of wavelengths, making it an ideal choice for optical applications.
