Cardek is based in South Africa and has manufactured and supplied fused silica refractory shapes to coke producers around the world, including ERDEMIR. Cardek has the capacity to manufacture upwards of 1,000 tons of shaped fused silica products per year.
Fused quartz, also named silica, is a noncrystalline form of silicon dioxide (SiO2). High purity is essential for fused quartz, which is mostly determined by the raw material, the manufacturing method and subsequent handling procedures.
Machined Glass Specialists was founded by people who grew up in the industrial glass business and is a true custom fabricator of quartz, silica, and borosilicate since 1989. Our fusedquartz technicians began fabricating quartz shortly after the process was developed in the mid 1960s.

Fused silica's broad transmission spectrum makes it desirable for solar concentrator optics. A fourphase project is underway to create an optical manufacturing process that ensures maximized optical transmission for fused silica.
Since 1971, George Ford Sons, Inc. has been a leading manufacturer of fused silica tempering oven rollers. Headquartered in the Philadelphia region, the company supplies glass and oven manufacturers worldwide with new and refinished rollers that allow clients to produce the highest quality glass products.
OHARA QUARTZ is manufactured according to the VAD method (axial vapor phase deposition). Due to production process our silica shows very good properties regarding high purity, high heat resistance, high transmission and high refractive index homogeneity.
Custom Glass Wafer Fabrication. Sydor Optics has decades of experience polishing precision glass wafers. Aside from standard size glass wafers such as 100mm, 150mm, 200mm and 300mm, Sydor Optics can provide custom wafers with diameters up to 450mm and thin wafers with thicknesses down to (± ).
Fused synthetic quartz glass for semiconductor manufacturing is created using pure, natural crystalline silica, such as sand or rock crystal. The silica is melted using either an electrically heated furnace, in which case electrically fused quartz is produced, or a gas heated furnace, in which flame fused quartz .
