Borosilicate, Quartz, and Sapphire Glass for Industrial Applications Overview
Borosilicate glass is an extremely durable glass, which is why it is frequently used in both the chemical and general industries. We offer you borosilicate glass in tempered form according to DIN 7080 and DIN 7081 (MAXOS®). If you require dimensions outside of these standards, we can manufacture the glasses from Suprax8488 blanks (borosilicate glass from the manufacturer Auer Lighting) or from Borofloat glass. Borosilicate glass according to the standards DIN 7080 and 7081, as well as soda-lime glass according to DIN 8902 and 8903, undergo a thermal tempering process (hardening). This results in a change in internal stress in the glass, meaning that its flexural strength increases. Tempered glass is also referred to as safety glass because, in the event of breakage, no large sharp pieces are formed, but rather small blunt fragments. We also refer to this as single-pane safety glass (ESG glass), which, due to these properties, enjoys particularly high popularity in the industry and chemistry. In addition, borosilicate glass is characterized by its good chemical and temperature resistance. Tempered borosilicate glass can be used for continuous operation at a maximum of 280°C, temporarily up to 300°C, and even up to 320°C when mica protected. Borofloat glass without safety tempering can be used continuously at temperatures of 450°C and temporarily up to 500°C. In contrast, soda-lime glass according to DIN 8902 and 8903 is only suitable for temperatures of up to 150°C.
Among the most chemically resistant technical glasses for us is quartz glass SiO2 (also referred to as fused quartz glass), which, similar to borosilicate glass, has a low thermal expansion coefficient. Quartz glass is also only attacked by a few acids and can withstand temperatures of up to 1100°C, unlike other technical glasses. In quartz glass, we must distinguish between natural quartz glass and synthetic quartz glass. Synthetic quartz glass is produced from pure silicon tetrachloride (SiC14) in a flame pyrolysis process. For natural quartz glass, on the other hand, rock crystal is ground into powder and melted using a hydrogen/oxygen flame. Quartz glass has many positive properties, such as high temperature resistance, good temperature cycling resistance, a low thermal expansion coefficient, and high purity. Quartz glass not only has particularly good chemical resistance but also good light transmittance. Therefore, quartz glass is often used in optical applications, as it offers outstanding optical properties in the ultraviolet, visible, and infrared wavelength ranges. Because of these properties, it is also frequently used in laser applications. Thus, quartz glass is among the frequently used technical glasses in many fittings for high-temperature applications.
Sapphire glass belongs to the most important technical glasses due to its exceptional hardness. It is significantly more resistant than borosilicate glass and also quartz glass. Sapphire glass is the second hardest transparent material after diamond. It is much more scratch-resistant than other types of glass. In addition to technical applications, it is often used as optical glass or as watch glass. Sapphire glass is made from high-purity synthetic aluminum oxide and has a crystalline structure, unlike other types of glass. Unfortunately, the production of sapphire glass is quite complex, which makes it relatively expensive. At high temperatures of up to 2000 degrees Celsius or in applications where extreme chemical purity is required, there is no alternative to sapphire glass.
