Quartz plate

The applications for fused quartz plates are frequent; they include window plates, heat shields and substrates. A fused silica plate made by Heraeus is available in a large variety of sizes and material grades.
Direct drawn quartz glass plates are electrically fused in a single step and provide a transparent cost efficient solution for many applications.
Fused silica plates cut from solid ingot or block material provide a large variety of shapes, sizes, surface finishes and material grades.
Heraeus Quarzglas offers to water jet, or laser cut fused silica plates to customer desired specifications. Grinding, polishing and fire polishing is availble upon request.
