Plastic crucibles for laboratories - Import export

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

Ceramic crucible is the use of high purity powder, trace elements added, from the phase structure and microstructure of modified production.A smelting vessel. Products are aluminum oxide crucible and fully stabilized zirconia porous crucible, the former is mainly used for smelting and laboratory Firing other high melting point material, which is mainly used for the melting temperature with Pt,Rh, Au and other precious metal.
