Customized Insulating 99% Bn Boron Nitride Ceramic Crucible Cup¹

Product Description Boron nitride is an excellent self-lubricating ceramic that can withstand high temperatures and maintain its lubrication capabilities in high vacuum environments.Usually composed of hexagonal boron nitride (P-BN), it has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dissipation material and high temperature insulation material.Due to its high thermal and chemical stability, boron nitride crucibles are used in high temperature applications. Boron nitride crucible can withstand high temperatures in the high vacuum environment, plus it has excellent corrosion resistance and electrical resistance. Thus, boron nitride ceramic crucible is an ideal choice in a wide range of industries, such as:Nonferrous & ferrous metals such as Al, Bi, Ge, Sb, Sn, Cd, Pb, Ni, Zn, Cu, Mg, Im, Fe, and Stainless Steel.Glass melt, Soda glass, CryoliteSilicon molten salt, fluoride, slagBoron Nitride Crucible Advantages:1.Low wettability to molten metal2.Relatively high thermal conductivity with low thermal expansion3.Relatively high thermal shock resistance4.Extremely high working temperature with proper inert gas protectionThe working temperature of the boron nitride ceramic crucible is 1900°C under vacuum and 2100°C under atmosphere protection. Nitrogen or argon atmospheres are best, it makes have the longest life.The boron nitride crucible has strong thermal shock resistance, 1500°C fast cooling without cracking, and 1000°C furnace holding for 20 minutes, taking it out and blowing and fast cooling for hundreds of times continuously without cracking.   ProPropertiesUnitUHBHBBCBMSBMABSCBMZBANMain Composition-BN>99.7%BN>99%BN>97.5%BN+Al+SiBN+Zr+AlBN+SiCBN+ZrO2BN+ALNColor-WhiteWhiteWhiteWhite GraphiteWhite GraphiteGreyish-GreenWhite GraphiteGreyish-GreenDensityg/cm31.622.0-2.12.2-2.32.25-2.352.4-2.52.8-2.92.8-2.9Three-Point Bending Strength  MPa1835356565809090Compressive Strength MPa458570145145175220220Thermal Conductivity W/(m·k)3540323535453085Thermal Expansion Coefficient (20-1000°C)10-6/K1.51.81.6222.83.52.8Max Using Temperature(°C)900900900900900900900900         In Atmosphere21002100210017501750180018001750         In Inactive Gas18001800190017501750180018001750         In High Vacuum                  (Long Time)        Room Temperature Electric Resistivity  Ω·cm>1014>1014>1013>1013>1013>1012>1012>1013Typical Application-Nitrides SinteringHigh Temperature FuranceHigh Temperature FurancePowder MetallurgyPowder MetallurgyPowder MetallurgyMetal CastingPowder MetallurgyHigh Temperature Electrical Furnace Components--√√√√√√√Metal Vaporize Crucible  √√    √The Container of Metal -√√√√√√√√ or Glass MeltingThe Casting Mould Components of The Precious Metal and Special Alloy.---√-√--√High Temperature -----√-√√ Support PartNozzle and Transport Tube of The Melting Metal--√√√√√√√Nitrides Sintering-√------- (Sagger and Setter Plate)e Unit HB BC BMS BMA BSC BMZ BA
