The fused silica wafers are suitable for many optical applications because of their excellent optical transmission characteristics. Fused silica also has excellent chemical resistance against a wide variety of solvents, as well as exceptional heat resistance, with high dimensional stability over a wide temperature range thanks to its ultra low thermal expansion coefficient.\u003c\/p\u003e\n\u003cp\u003eOrder fused quartz wafers with best price on the \u003cspan\u003emarket from a trusted materials supplier, \u003cstrong\u003eMSE Supplies\u003c\/strong\u003e.
