Quartz & Glass


  • Overview


Quartz is a nonconductor with small gas content and little alkali ingredient which gives rise to electrical conduction and called 'silica glass'.

Highly purified quartz glass fiber has low light absorption and excellent light transmission, so it is an important light fiber material and mainly used for dry etching and diffusion processes in semiconductor sector.

Taking advantage of the heat resistance, thermal shock resistance, and chemical resistance, quartz is used for physical and chemical laboratory equipment, watches and communication equipment as quartz vibrator and optical fiber is increasingly used for optical parts as per the advancement of optoelectronics.
