Fused Quartz Discs

Quartz Scientific, Inc. (QSI) manufactures commercial grade ground and polished fused quartz discs from 1/4" to 22" diameter. The plate thickness for these quartz glass discs are available from cover slides a fraction of a millimeter to heavier pieces more than 3/4". Optical grade fused quartz discs must be specified. As well, rough cut quartz glass discs must be specified if desired.

QSI fused quartz disc purity levels (99.998% SiO2) are attained by careful screening of raw material, meticulous attention to detail, and stringent quality control throughout the various manufacturing stages. QSI also stocks and supplies quartz glass in the other forms such as tubing, rods, ingots, plates, and cylinders. From thin-wall boiling and distilling flasks to heavy-wall diffusion tube used to process semiconductor wafers at furnace temperatures in excess of 1200 degrees C. QSI offers custom fabrication of fused quartz discs and other products to customer specification and configuration.

Most products are available in opaque, transparent and arc fused (Type TPL) forms. QSI fused quartz disc products meet or exceed all industry standards for physical, thermal, chemical, mechanical and electric properties.
