Quartz glass is a high-tech material for special applications and for nanolithography
Pure quartz glass (or better synthetic fused silica) consists exclusively of silicon and oxygen (SiO2). Superficially, it can barely be distinguished from ordinary glass; however it has significantly different characteristics, such as resistance to chemicals, temperature and radiation, and optical transmission.
“Quartz glass is one of the purest technical materials used in industry today. Even the slightest contamination can lead to major process faults in the applications or even cause total failure,” says Dr. Ralf Takke, Vice President of the Optics Division at Heraeus Quarzglas. This business segment is one of the few specialists to master all aspects of this extraordinary material and produce it using all common processes in quality grades that are globally unique. With over 5,000 standard products for the semiconductor sector, the quartz glass specialist is amongst the leading technology companies in the application, product engineering, repair, measurement, cleaning and recycling of quartz glass.
