Large Size Synthetic Quartz Crystal

Quartz is relatively abundant in nature, but the optical grade nature quartz tend to be less and less. The limited supply and high cost of large size natural quartz have resulted in the development of synthetic crystal quartz. Single Synthetic Crystal Quartz is grown by hydrothermal method in autoclaves. The autoclave works on the principle of hydrothermal gradients with temperatures in excess of 400 °C and pressures exceeding 1,000 atmospheres. Sythetic quartz has better UV transmission and higher damage threshold.

OptoCity offer as cut Quartz plate as well as precisely polished products.

Note: Quartz should not be processed or used at temperatures greater than 490 °C. At temperatures >490°C, Crystal Quartz starts to revert to glassy state, a process which is complete by 530°C. At this time, as annealling is unlikely, fracture of component is probable.
