TSC fused quartz is manufactured by flame fusion from refined natural quartz crystal.
The long furnace residence time guarantees a material with a low level of inclusions and bubbles, resulting in a high product yield for the quartz fabricator.
Heraeus transparent ingots are available in rectangular, round and hollow shapes and a wide range of sizes. Ingots can be cut and ground or lapped to make blanks in a variety of shapes including rectangular or squared plates, disks and rings.
