Description
Quartz plates and discs are widely used on optical appliances, for quartz fabrication and in semiconductor industry.
Based on the production methods, three different types of plates are provided:
Grade QL410 is an Electric Fused type made from cutting the fused tubes made by continuous fusion process. It has similar properties as Grade QL110 Tube. Both plates and disks can be surface-polished. The maximum size of a single piece is 500mmx500mm. 4+ pieces can be welded together for the request of larger size.
Grade QL420 is a Flame Fused type cut from flame fused ingot. It combines the strength of QL410 type with higher thermal resistance. The maximum diameter of the flame fused ingot is 450mm which determines the maximum diameter of the disks and the maximum length of the plates cut from the ingot is 400mm.
Quartz Rings and flanges with different sizes are also available of this grade.
Grade QL630 is a Synthetic type which is made from synthetic ingot. It has high properties in chemical purity, optical transmission and bubble content, etc. The maximum diameter of this type of ingot is 350mm, thus the maximum diameter of a single piece of disk and the maximum length of a plate cut from the ingot is up to 300mm. Synthetic fused silica blocks are also available at different sizes for optic fibre industry.
