High Purity Quartz Rods

High Purity Quartz Rods

Fused quartz and fused silica glass are two distinct but closely related materials used in a variety of industrial and scientific applications. Despite their similar names, they have distinct properties and manufacturing processes.

Fused quartz is a high-purity material made from natural or synthetic quartz crystals. It is produced by melting the quartz at extremely high temperatures and then allowing it to cool and solidify. Fused quartz is known for its exceptional thermal and mechanical properties, high chemical purity, and excellent optical transparency. It is used in a wide range of applications, including semiconductor manufacturing, optics, and laboratory equipment.

Fused silica glass, on the other hand, is made by melting and then rapidly cooling silica, the primary component of quartz. This process results in a glass that is highly transparent and resistant to thermal shock. Fused silica glass is often used in optical applications, such as lenses and mirrors, as well as in the semiconductor and aerospace industries.

Quartz rod, which is also known as quartz tubing, is a type of fused quartz that is commonly used in scientific and industrial applications. It is made by heating and shaping fused quartz into a cylindrical shape, which can then be cut and machined into various sizes and shapes. Quartz rod is known for its high thermal and mechanical stability, making it ideal for use in high-temperature applications.

Overall, fused quartz, fused silica glass, and quartz rod are all important materials used in a variety of industries and scientific fields. Their unique properties make them ideal for use in applications where high purity, thermal stability, and optical transparency are required.


Diameter from 2mm- 50mm


  • High purity made of 99.99% pure Sio2.

  • Strong Hardness, Can reach Morse level 7.

  • High-temperature resistance can work under 1200°C continuously and for short time can even work under 1500°C.

  • Acid and Alkali resistance: Except for hydrofluoric acid, quartz glass does not react with any acid and base except hydrofluoric acid. The stability is 30 times of the ceramic, and 150 times of stainless steel.

  • High light transmittance, is different from 85%-95% depending on a different spectrum.

  • Excellent thermal shock stability, Small thermal expansion coefficient, it is only 5.5×10-7/℃.



Fused silica quartz glass rod is mainly used in electric light sources, electrical appliances (electric), semiconductor, optical communications, military industry, metallurgy, building materials, chemical, machinery, electricity, environmental protection, and other fields.
