Introduction UV transmission is one of the most important optical properties of quartz glass. Many common glass materials absorb ultraviolet light, limiting their use in UV-based systems. Quartz glass, however, provides excellent ultraviolet transmission because of its highly stable silica structure and low absorption characteristics. This makes quartz glass widely used in: UV sterilization systems UV lamps Optical instruments Photochemical equipment Semiconductor manufacturing systems When selecting [...]

Introduction Chemical resistance is one of the key reasons quartz glass is selected for demanding industrial applications. When materials are exposed to chemicals, they may experience corrosion, surface damage, contamination, or loss of performance. For industries such as semiconductor manufacturing, laboratory research, and chemical processing, material stability is critical. Quartz glass provides excellent chemical durability because of its stable silicon dioxide (SiO₂) structure. This allows quartz [...]

Introduction Thermal expansion is one of the most important properties when selecting materials for high-temperature applications. When a material is heated, it expands. When it cools, it contracts. If this dimensional change creates excessive stress, components may deform, crack, or fail during operation. Quartz glass is widely used in demanding applications because it has an extremely low coefficient of thermal expansion compared with most glass materials. [...]

Introduction Quartz glass manufacturing is a specialized process that requires precise control of temperature, material handling, forming methods, and finishing processes. Unlike ordinary glass production, quartz glass processing requires extremely high temperatures because silicon dioxide has a very stable molecular structure. The final performance of a quartz component depends not only on the material itself, but also on how it is formed, machined, polished, and inspected. [...]

Introduction Quartz glass is one of the most widely used advanced glass materials in high-temperature, optical, semiconductor, and laboratory applications. Unlike ordinary glass, quartz glass is mainly composed of silicon dioxide (SiO₂), giving it unique properties such as extremely low thermal expansion, excellent temperature resistance, high optical transmission, and outstanding chemical stability. These characteristics make quartz glass suitable for demanding applications where conventional glass materials cannot [...]

Introduction Fused quartz and fused silica are two terms that are often used interchangeably in the quartz glass industry. Because both materials are mainly composed of silicon dioxide (SiO₂), many engineers and buyers assume they are exactly the same material. In most industrial applications, the difference is not the chemical composition but the manufacturing method, raw material source, and industry terminology. Both materials offer excellent thermal [...]

Introduction Quartz glass and borosilicate glass are two widely used glass materials in laboratories, industrial equipment, optical systems, and high-temperature applications. Although both materials offer excellent chemical resistance and thermal stability compared with ordinary glass, their properties are significantly different. The main difference is that quartz glass is made from high-purity silicon dioxide (SiO₂), while borosilicate glass contains significant amounts of boron oxide (B₂O₃) and other [...]

Introduction Large diameter quartz tubes are widely used in semiconductor furnaces, solar PV equipment, laboratory furnaces, and high-temperature industrial systems due to their excellent thermal stability, chemical resistance, and low contamination characteristics. FGQuartz manufactures custom fused quartz tubes with diameters from 5 mm to 1000 mm, supporting different wall thicknesses, lengths, surface finishes, and machining requirements according to customer drawings. Large quartz tubes are commonly used [...]

Modern laboratories demand materials that can perform reliably under some of the most demanding scientific conditions. Whether researchers are analyzing trace elements, developing new pharmaceutical compounds, testing advanced materials, or operating high-temperature furnaces, the quality of laboratory equipment directly influences the accuracy and repeatability of experimental results. Among the many engineering materials available today, quartz glass has earned a unique position. It is found in research [...]

Quick Answer A quartz tank is a fabricated fused silica vessel used where process media—hot acid, alkaline etch, plating solution, high-purity reagent—demands thermal stability, chemical inertness and low extractables that metal and fluoropolymer cannot both deliver. FGQuartz builds quartz tanks to customer drawing: rectangular or cylindrical body, welded flange rim, bottom drain or side port, optional heating jacket, sight window and agitator port, then fire-polished on [...]
