Adopting imported sand or domestic high-purity sand with very high purity, high transmittance in both UV and IR areas. High transmittance in both the UV and IR zones, very few air lines and bubbles on the surface, and very low hydroxyl content (<1ppm). so that it can be used in large, medium and small power bulbs can maintain a long life. The very low hydroxyl content (<1ppm) enables them to maintain a long life in large, medium and small power bulbs.
It is a doped transparent quartz tube that is approximately 150°C cooler than conventional quartz glass materials, and its extreme dimensional tolerance control provides superior processability for high-speed, fast-machining lines, as well as low hydroxyl, UV-C filtering properties.
Solar grade opaque quartz ingots are the base material for making insulating quartz components. It is commonly used in oxidizing and diffusion treatments.
UHP quartz tubes are made of high purity natural quartz sand with a total impurity content of about 10 ppm. The contents of alkali metals and hydroxyl groups are very low. It has stable performance under high temperature and high pressure. Finished lamps have the advantages of small size, high brightness, long life, etc.
Semiconductor grade high purity quartz sand is used in the production of standard semiconductor grade quartz tubes, quartz rods, quartz crucibles and superconductor grade quartz tubes and quartz rods.
It is a kind of doped transparent quartz tube that absorbs part of UV-C and has a high transmittance
(typical transmittance > 88%) at 254nn in the ultraviolet region, which can satisfy lamp special requirements at the ultraviolet region.
