Application:
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 process.
