Product Name: Pyrolytic Boron Nitride Mbe Crucible Model NO.: Pyrolytic Boron Nitride MBE crucible Type: Pyrolytic Boron Nitride Crucibles Refractoriness: Refractoriness> 2000 Color: White Shape: Boat Certification: CCC, CE, ISO, ISO9001 Properties: Pyrolytic Boron Nitride Trademark: KT Transport Package: Export Safe Box Packing Specification: 0.1kg Origin: China HS Code: 6909190000 Product Description Pyrolytic Boron Nitride crucibles1. Product Instruction Pyrolytic Boron Nitride (PBN) is akind of advanced ceramic, can be produced with 99.999% purity in high density. It made by ammonia and Boron halide through Chemical Vapor deposition(CVD) process in high temperature and high vacuum condition:NH3 +BX3=BN+3HX ,it can be produced as PBN plates, and also can be produced as PBN final products directly like crucible, boat, coating, etc. 2. Main Features It's different from BN, there is no traditional process of hot pressing, no need any kinds of agglutinant, so the products have very obliviously features as follow: Non-toxic and tasteless High purity(>99.999%) No reaction with acid, alkali, salt and other organic reagent at room temperature A little corrode in melt salt and alkali, but it can resistance any kind of acid in high temperature. No reaction with melt metal, semiconductor and other compound. Excellent oxidation resistant below 1000ºC Excellent thermal shock resistance Can be used in high-temperature, no sublimation point, will be decompose into B&N High electrical resistance, good electrical insulating property Smooth surface, pore-free, not melt with most of semiconductor3.
