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.

They are also used in metal casting because it bonds well to metals, as a sandwich of metal borides or nitrides is formed.
 

The benefits of using a boron nitride crucible are its low wettability to molten metal, relatively high resistance to thermal

shock, and conductivity with low thermal expansion. Another advantage of boron nitride crucibles is their very high operating
temperatures and appropriate inert gas protection (temperatures above 3000°C have been recorded).
Boron Nitride Flat Bottom Crucible is used for melting aluminum, zinc and other alloy smelting, replacing graphite crucible.

The boron nitride Evaporating boat crucible has strong resistance to thermal shock and will not crack when quenched to 1500 degrees. It will not crack if it is kept in the furnace at 1000 degrees for 20 minutes and taken out to be blown and quenched continuously for hundreds of times.
Note: Boron nitride crucible is easy to absorb moisture and cannot be stored in humid areas. It cannot be washed with water. It can be wiped directly with sandpaper or wiped with alcohol.
