Hot pressed boron nitride ceramic rod could withstand higher temperature in vacuum than lower purity and composite boron nitride products. However, the composite materials generally enhanced mechanical properties such as bending strength, and the high temperature performance in air.
Due to the low wetability with metals, boron nitride rod is an ideal material for metal melting works, especially for high purity material metal in vacuum.
Boron Nitride Properties
Boron nitride ceramic rod is chemically and has relatively good thermal conductivity, low thermal expansion and microwave clarity. Boron nitride bar rod can be quickly machined as well. Moreover, glass, salts and the rest of liquid metals are non-wetting. This ensures that neither of these compounds can be moistened, and it is far more immune to chemical assaults.
Boron Nitride Rod Advantages
BN rod is easily machinable. It has high performances:
– Low wetability to molten metal
– Low dielectric constant
– Relatively high dielectric strength
– Relatively high thermal conductivity with low thermal expansion
– Relatively high thermal shock resistance
– Extremely high working temperature with proper inert gas protection (>3000C has been recorded).
– Chemical Vapor Deposition (CVD)
Boron Nitride Rod Applications
Boron Nitride ceramic can withstand high temperature in the high vacuum environment, plus it is chemically inert — it has excellent corrosion resistance and electrical resistance. Thus, Boron Nitride ceramic product is an ideal choice in a wide range of industries, such as:
-Evaporator Boats
-Nozzles for nonferrous metals metallurgy industry
-Electric insulators in the vacuum environment
-Insulators for high-temperature furnace
-Spacers for glass melting
