Description

Applications
Tungsten has a unique property of which it's melting point can reach ***0 tungsten crucible is widely applied in high temperature vacuum furnace melting environment such as sapphire growing furnace, quartz glass melting furnace, and rare earth melting furnace. The working temperature of tungsten crucible is above ***0. 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.
Crystal growth is a major stage of a crystallization process, which typically follows an initial stage of either homogeneous or heterogeneous (surface catalyzed) nucleation.
Crystal growth is a significant step for the semiconductor industry as well as for optical applications and solar industries. Sapphire single crystals are used for high power laser optics, high pressure components and substrates for LEDs. Aluminum Nitride (AlN) single crystals are the principal components for fabricating UV-LEDs and laser diodes (LDs).
We can produce many varieties of tungsten and molybdenum crucibles for single crystal growing process as a high temperature durability container in this application with its best properties.
