Fused Quartz Crucibles
Quartz Scientific, Inc. (QSI) manufactures semiconductor grade fused quartz crucibles in a variety of sizes, with or without lids, and from 10 to 150 ml of capacity. Various thicknesses are available for these quartz glass crucibles. Fused quartz crucibles come in low form with lid, tall form without lid, clear quartz, and clear quartz glass crucibles with lids.
QSI fused quartz crucibles’ 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, discs, and cylinders. From thin-wall boiling and distilling flasks to heavy-wall diffusion tubes used to process semiconductor wafers at furnace temperatures in excess of 1200 degrees C. QSI offers custom fabrication of fused quartz crucibles and other products to customer specification and configuration, and repairs fused quartz glass crucible products when feasible.
Most products are available in opaque, transparent and arc fused (Type TPL) forms. QSI fused quartz crucible products meet or exceed all industry standards for physical, thermal, chemical, mechanical and electric properties.
