The large-sized quartz crucible developed by the Chinese manufacturer of super-sized sapphire crystals successfully rolled off the production line

On September 16, 2021, the large-size quartz crucible developed by ZJJS Crystal Materials Technology Corporation was successfully launched.

The large-size quartz crucible produced by ZJJS is an indispensable basic material for drawing large-size single crystal silicon rods of semiconductor and photovoltaic levels, and provides a technical basis for the manufacture of large-diameter silicon wafers in China. The quartz crucible of 28 to 40 inches produced by the company can meet the needs of customers for products of different models and specifications.
