Large diameter quartz tube: large diameter quartz tube is a special type of transparent quartz tubes. Large diameter quartz tube with high temperature corrosion resistance, thermal stability, good transparency and good electrical insulation and a series of excellent physical and chemical properties, is widely used for special metal smelting molds, precision chemical pipelines, electric furnace tubes, diffusion tubes, cleaning tanks and production equipment, square cylinder, quartz plate and so on.Large diameter quartz tube has been declared as a patent. In production, the large diameter quartz tube turned out contains silica purer than 99.98%. With lesser bubble gas line and magazine content, it can also be further cut to the expansion of large-diameter quartz tube plastic tube to meet the semiconductor, photovoltaic and other high-tech industry, application requirements, and gradually replace the imported large diameter quartz tube.
