Good thermal and mechanical property,accurate dimensional tolerance,and OH content is available according to different needs
The surface of this kind of tube is smooth and the tube is colorless.The properties of the tube are:high purity(SiO2>99.99%),abarasion resistance(any acid except HF acid),fire resistance(softening point is 1700 centigrade),low coefficient of thermal expansion(5.5*10-7/centigrade).The surface can be done with gold plating.OH content (1-160ppm)is available according to the requirements of customers.
It is widely applied at halogen lamp,mercury lamp,printer lamp tube,stage light,chemical tube,and heat-resistant utensils,etc.
