Mo and W crucible 99.95% purity Smooth degree 3.2 use temperature Mo 1800 W 2200 highest temperature Mo 2200 W 2400  Molybdenu crucible is applying in single crystal growing melting environment,such as LED sapphire and AlN growing. 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.1)Dimensions and tolerances Unit:mm
