About Us

Changfei Quartz uses non-contact stretching technology to prepare synthetic quartz pipes, which have high geometric dimension accuracy, excellent optical refractive index control, and extremely low impurity content

Using imported natural quartz sand and electric melting process, we provide high-purity, low bubble rate, and low OH content quartz materials for semiconductor use. They can be used in high-temperature resistant and semiconductor etching plasma areas, as well as semiconductor quartz components.

Changfei Quartz Technology (Wuhan) Co., Ltd., established in December 2022, is a subsidiary of Changfei Fiber Optic Cable Co., Ltd. (stock code: 06869.HK, 601869. SH), specializing in the research and development, production, testing, sales, and service of high-end quartz material products.

The groundbreaking ceremony of Changfei Quartz Wuhan Factory marks the official start of construction and the beautiful vision of the future development of the quartz industry.

Changfei Quartz Ezhou Factory has started construction, opening a new chapter in the development of the quartz company.

Has ultra-low hydroxyl content (OH)<1ppm) and excellent optical performance can achieve high optical uniformity, low stress birefringence, extremely high transmittance from deep ultraviolet (193nm) to near-infrared (2800nm) bands, low weak absorption coefficient, and strong resistance to gamma radiation.

Customizable high optical uniformity, low stress birefringence, high transmittance in the 355nm, 532nm, 1064nm and other wavelength bands far from the hydroxyl absorption peak, with a maximum aperture of meters.
