Domed / Flamed Quartz Glass Tube

Domed / Flamed Quartz Glass Tube
Product Detailed
we can make different Domed / Flamed Quartz Glass Tube with further processing of polishing and flaming. According to consumers requirements, we can make different Domed / Flamed Quartz Glass Tube with further processing of polishing and flaming. Polishing - flat or radius surfaces.  (both spherical and cylindrical)  The standard Commercial Grade Polishing is typically a flatness of 3 to 5 waves per inch and parallelism of 3 arc minutes or better.  Our Optical Grade Polishing is a flatness of 1/2 wave per inch and parallelism of 1 minute or better.  The surface quality specification is also much higher:  60/40 for our optical quality polishing, and 80/50 for our commercial quality.  If your application demands, we have the capabilities of a 10/5 surface and 1/20 wave flatness. Flaming - Flame fusion is a 2-step process. The first process is the natural quartz sand or synthetic SiC14 is melted in hydrogen/oxygen (H2/O2) flame into a solid round ingot. The second process is to further shape the ingot into various shape and dimension. Flame the quartz glass contains an abundant amount of hydroxyl (OH) as a result of the direct contact between the H2/O2 and the silica raw material. This OH content can not be reduced by annealing and its presence lowers the viscosity and infrared transmission. The flame quartz has no drawing line and very low bubble content.
