Product Descriptionhigh purity Sapphire crystal tungsten crucible made in changsha


Specification of Sapphire crystal tungsten crucibleThe furnace industry has seen a remarkable growth in the production of custom-made, high temperature vacuum or argon atmosphere furnaces for growing sapphire crystals used in manufacturing of LEDs. These furnaces have unique and demanding hot zone designs for melting alumina in crucibles for precise, highly controlled crystal growth.Mingguan metal is fully aware of the various sapphire crystal growing methods and supplies components to the customers accordingly.The hot zones in sapphire growing furnaces use molybdenum and tungsten products for furnace components and fixtures. These high temperature materials are characterized by their high thermal and electrical conductivity, low coefficient of thermal expansion, and excellent strength and stability at temperatures above 2,000°C.Customer specific furnace components and fixtures for high temperature furnaces are uniquely designed and are supplied by Mingguan metalDensityWorking temperatureDiameterCubageSintering tungsten crucible18.0-18.5g/cm31800-2600DC100-500mm0.4-100 litresForging tungsten crucible18.5-19.0g/cm31800-2600DC18-150mm2-500MLDelivery conditionSpecificationToleranceThicknessRoughnessDiameterHeightDiameterHeightmm (um)Sintering10-50010-750+/-5.0+/-5.08-20<3.5Sintering finishing10-45010-550+/-5.0+/-5.07-18<2.5Special sizes can be manufactured according to customers' requirements.Pictures of our Sapphire crystal tungsten cruciblewe can provide Other Curcibles below:
