2. Tungsten plate Application
Tungsten has a unique property of which it's melting point can reach 3410 tungsten,
is widely applied in high temperature vacuum furnace melting environment such as
sapphire growing furnace, quartz glass melting furnace, and rare earth melting furnace.
For sapphire crystal growing furnace, high-purity, high-density, no crack,
tungsten crucible with other features of exact measurement and smooth surface
has decisive influence on the success of crystal growth, quality control of pulling crystal, discharging
and service life during sapphire growing.
