Why can quartz glass heating tubes be heated?
The quartz tube expansion coefficients are very small, not burst into the water immediately after heating. It is used in heating equipment, in order to make the intermediate electric wire electric heat emitted by the radiation can be fully out, there is a quartz tube, it is the heat emitted by the electric heating wire with radiation, so use the opal quartz tube do electric heating tube, because it is white, inside of the electric heating wire is not easy to see, in fact there is a heating wire. A transparent quartz tube with an ultraviolet characteristic, so ultraviolet germicidal lamp with good transparent quartz tube processing.
Heating or electric heating, just inside the quartz tube.
Not that it can be heated, but that it can be burned, and that the high temperature is not afraid of it
