About us
-
Lianyungang Haisheng Quartz Tech Co. Ltd stems from the former state-owned Donghai Quartz Glass Product Factory. Haisheng Quartz(abbr. Lianyungang Haisheng Quartz Tech Co.ltd) is a member of Quartz Industry Associate, and it covers R&D, production and marketing. At present there are 6 production line. Annually 700t quartz tube(/fused silica tube) and quartz silica plank(quartz plate, quartz wafer, quartz substrate) are being produced.
A novel technique about vertically producing quartz plate with fused silica was invented by Haisheng Quartz Co., and the intellectual property right is held.
Main products include quartz plate(/quartz plank) 2～20mm thick, quartz tube(/fused silica tube) diameter 2.5～100mm, quartz rod, UV tube, none-ozone tube, low OH tube, opaque tube, etc.

Quartz panel (Quartz sheet/window/plate/disk)
Quartz panel is characterized by its transparency to quite wide spectrum, including ultraviolet (UV), visible light, and infrared (IR). Quartz panel is also characterized by its stable endurance in high temperature and chemical challenging environments, with a quite low thermal expansion. Due to these capabilities, quartz panel is a qualified optical material in many demanding applications.
Quartz plank is vertically produced in our factory, subsequently it can be post-processed(cutting, welding, polishing, annealing, etc) into sheet, plate, lens, window, pane, disk, substrate, etc. SiO2 content is above 99.99%, Mons' hardness scale is 7. More than 90% of visible light can be passed. It can endure high temperature (as high as 1100°C) with a low thermal expansion coefficient. Different shapes such as Prism, lens and disk are available.
Quartz has been widely used in illumination, laser, sterilization, lab equipment, insulator, chemical equipment, heater, etc. More details about fused quartz can be found on Wikipedia page.
Properties
1. Endurance of high temperature. Fuse quartz begin to soften at about 1700°C. It can work at 1100°C for a long period while for a short period it can endure 1450°C.
2. Anti chemical erosion. Almost none acid react with quartz, except for HF. Due to the construction of pure SiO2, the anti-acid capability of quartz is 30 times better than ceramics, and 150 times better than stainless steel. Its chemical inertia or stabilization is hardly comparable by any other common material.
3. Low thermal expansion. The thermal expansion coefficient of quartz is so low that it can endure steep temperature change. For example, heat a quartz panel to 1100°C and than immerse it into water at normal temperature, it won't crack!
4. Spectrum transparent. Quartz is transparent to wide spectrum, from IR to UV. More than 90% of visible light energy can pass, and more than 80% of UV can pass.
5. Good insulator. Resistance of quartz is 10000 times of normal glass. Good insulating performance even at high temperature.
