Fused quartz and fused quartz glass are two different but closely related materials used in various industrial and scientific applications. Although they have similar names, they have different characteristics and manufacturing processes.
Fused quartz is a high-purity material made from natural or synthetic quartz crystals. It is made by melting quartz at extremely high temperatures and then cooling and solidifying it. Fused quartz is known for its excellent thermal and mechanical properties, high chemical purity, and outstanding optical transparency. It has a wide range of applications, including semiconductor manufacturing, optics, and laboratory equipment.
On the other hand, fused quartz glass is made by melting and rapidly cooling silica (the main component of quartz). This process produces highly transparent and heat-resistant glass. Fused quartz glass is typically used in optical applications such as lenses and mirrors, as well as in the semiconductor and aerospace industries.
Quartz rod, also known as quartz tube, is a type of fused quartz commonly used in scientific and industrial applications. It is made by heating quartz and shaping it into a cylindrical shape, which can then be cut and machined into various sizes and shapes. Quartz rod is known for its high thermal stability and mechanical stability, making it ideal for high-temperature applications.
Overall, fused quartz, fused quartz glass, and quartz rod are important materials used in various industrial and scientific fields. Their unique properties make them ideal for applications that require high purity, thermal stability, and optical transparency.
High purity made of 99.99% pure silica.
Strong hardness, up to Mohs 7.
High temperature resistance, can work continuously below 1200℃, and even work below 1500℃ for a short time.
Acid and alkali resistance: Except for hydrofluoric acid, quartz glass does not react with any acid or alkali other than hydrofluoric acid. Its stability is 30 times that of ceramics and 150 times that of stainless steel.
High light transmittance, ranging from 85% to 95% depending on the spectrum.
Excellent thermal shock stability, small thermal expansion coefficient, only 5.5×10-7/℃.
Fused quartz glass rods are mainly used in electric light sources, electrical appliances (electricians), semiconductors, optical communications, military industry, metallurgy, building materials, chemical industry, machinery, power, environmental protection, and other fields.
