Milky White Quartz Tubes For Heater
The milky white quartz glass tube is made by high-temperature melting of vein quartz and quartz sand as raw materials, containing SiO2 more than 99.5% SiO2, as well as large bubbles with a diameter of 0.15-0.3mm and small bubbles with a diameter of 0.004-0.08mm. Due to the inconsistency between the refractive index of bubbles and glass, light scatters and appears milky white and opaque.
