Fire Resistant Quartz Glass Fused Silica Plate For Camera

A method for producing a large-diameter silica glass is to put quartz sand raw material into a crucible of a melting furnace, reduce the crucible to a minimum through the upper cover, and melt the molten material into a liquid, and the liquid is discharged at a high temperature and then discharged through a vent hole. Gas impurities and liquid impurities, the crucible is lifted through the upper cover, and the liquid enters the molding machine table for molding, and the raw materials are continuously added to the crucible, and the quartz glass mother tube is pulled down by the tractor to make the quartz glass main tube Input into the secondary molding machine for walking and expanding, and expand into a large-diameter glass silica glass with a wall thickness of 5 mm or more when Φ520 ±0.1 mm. Finally,the expanded quartz glass tube is sequentially cut off at both ends, acid Wash, ultrasonic cleaning, annealing.


The formation of quartz glass is a result of the high viscosity of the melt. Used in the manufacture of semiconductors, electric light sources, semi-conductive communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment and chemical instruments for high temperature and corrosion resistance, chemical, electronics, metallurgy, building materials and national defense industries. Very extensive.

High-purity quartz glass can be used to make optical fibers. With the development of semiconductor technology, quartz glass is widely used in various processes of semiconductor production. For example, the Czochralski method converts polycrystals into single crystal silicon; the cleaning bath used for cleaning; the diffusion tube used for diffusion, the grooved boat; the bell jar used for ion implantation, and the like.
