Transparent Quartz Glass Tube By Lianyungang Wangchong Quartz Products Co.,ltd.

With the use fusion technology and effective automatic controlled system, this clear quartz tube has the typical characteristics of high purity, good spectral transmission, well controlled dimension, lower OH and so on.. It serves as the first choice of heat resistant material for halogen lamps, mercury lamps, metal halide lamps and other quartz lamps. And further processing of trim cutting, fire polishing, bending and pinching and etc. can be done according to the requirement of customers. OH-content can be controlled within 20ppm\15ppm\10ppm\5ppm\2ppm according to the requirement of customers. Quartz glass is special industrial technology glass made by silicon dioxide and is one kind of excellent basal material.Quartz glass has series of excellent physical capabilities.For example: 1. Heating resisting. The softening point of quartz glass is 1730 degree,it can be used long under 1100 degree.And the highest using temperature can get up to 1450 degree in very short time. 2. Corrosion resisting. Quartz glass can not react with other acid material except hydrofluoric acid. Its acid resisting ability is 30 times of ceramic,and 150 times of stainless steel. Especially for its chemical stability under high temperature is better than any other projected material. 3. Heat stability is better. The coefficient of expansion is very small.It can bear exquisite changing temperature .Heat up quartz glass to 1100 degree,then put into normal temperature water and it will not broken.
