Product Description

Introduction of Boron Nitride ceramic crucible:

A boron nitride crucible suitable for the vaporization of aluminum, having a multi-walled structure comprising an outer wall and a thinner inner wall weakly bonded to the thicker outer wall. Because of this structure, the crucible is considerably more flexible than conventional single-walled crucibles and exhibits substantially improved thermal cycling characteristics and longer life. The crucible is produced by depositing pyrolytic boron nitride upon a mandrel having the shape of the desired crucible at a temperature of from about 1850° C. to about 2100° C. until a first layer of boron nitride of suitable thickness has been produced, interrupting the deposition of boron nitride upon the mandrel and lowering the temperature to below 1750° C., and then depositing additional boron nitride upon the mandrel at a temperature of from about 1850° C. to about 2100° C. to produce a second outer layer of boron nitride having a thickness greater than that of the inner layer.

 

Features and Benefits of Boron Nitride ceramic 1. Easily Machinable 2. Exceptional Heat Resistance 3. High Thermal Conductivity 4. Low Thermal Expansion, Excellent Thermal Shock Resistance 5. Outstanding Electrical Insulation - even at high temperatures 6. High wet resistance to molten metals, slags and glass 7. Extreme Corrosion and Wear Resistance High Temperature Environments: Temperature stability and excellent resistance to thermal shock makes BN the material of choice in the toughest high temperature environments such as equipment for plasma arc welding, diffusion source wafers, and semiconductor crystal growth equipment & processing. It can be used in vacuum environment for 1800 . Also, it can stand 2000 in gas protecting environment.
