Product Description

In the semiconductor industry, large diameter fused quartz tubes are widely used as materials of furnace chambers for processing silicon wafers due to their high purity and excellent heat resistance. QL**0LD is the series of large diameter tubes with all properties similar to QL**0. A full range of diameters, up to **0mm, is available in Quartz Link. These low cost tubes offer the level of purity, furnace life, processing temperature and other properties that semiconductor industry requires. Special heavy wall thicknesses used as bell jar sleeves are also available upon requests.
