Description





BN Boron Nitride Ceramic Crucible

The use temperature of boron nitride ceramic crucible in vacuum is 1800 degrees, and the use temperature under atmosphere protection is 2100 degrees. Nitrogen or argon atmosphere is the best and has the longest life. The boron nitride crucible is resistant to thermal shock, and will not crack when it is rapidly cooled at 1500 degrees. It will not crack if it is taken out of the furnace at 1000 degrees for 20 minutes and blow and quenched for hundreds of times.

Precautions for use:
1、The use temperature in the air should not exceed 1000 degrees, and the surface of boron nitride in contact with oxygen will peel off if it exceeds 1000 degrees.
2、Boron nitride is easy to absorb moisture. The crucible cannot be stored in wet areas and cannot be washed with water. It can be directly wiped off with sandpaper or scrubbed with alcohol.
3、Application direction of boron nitride crucible

Available materials:
1. Ferrous metals: iron, copper, aluminum, nickel, magnesium, bismuth, zinc, etc., alloys FE-CO-NI-SI CO-ZR-NB
2. It does not react with water or acid at room temperature. Boil with water and slowly hydrolyze to generate boric acid and ammonia
3. Rare earth, nitride

INNOVACERA supply all shapes of ceramic crucibles, welcome inquiry.
