Quartz glass rods are used to make special optical fibers and optics.

The continuous melting method can use raw materials with different characteristics to produce transparent quartz tubes and transparent quartz rods with good appearance and size, and can adjust the OH value through heat treatment. It can be used for the production of quartz lamps such as mercury lamps and halogen lamps, and electric heating of the outer tube. , Peninsula body products materials, optical fiber basic tubes, etc.
