On the production process of quartz rods, many customers want to know, then the quartz rods of the production process which? Today, by the technical staff to tell you about the quartz plate production process.

I plant experts said that the production process of quartz rods have a lot, here first introduced two:

1, two-step process The process is the gas refining and melting of the two processes together, that is, with a vacuum resistance furnace production of quartz lump, and then quartz lump resistance furnace in the second tube, can be made into 80-150mm Large diameter quartz glass tube for semiconductor technology.

2, doping process quartz glass is a single component of SiO2, only so many excellent performance, doping is to absorb ultraviolet light; there are some products such as laser lights, no ozone lights, etc., hope that quartz glass to absorb a certain band of ultraviolet light, but also To retain the other properties of quartz glass, which appeared in the doping process, doping elements are specific to absorb ultraviolet light, such as: Ti, Ce, Eu and other elements, and the amount is very small, generally only mixed with dozens to hundreds Ppm (1000 ppm = 1%), the general doping amount is 0.05% -0.2%.
