Boron nitride crucible is processed...
Boron nitride crucible is processed according to the size required by the customer after the boron nitride powder is hot-pressed and sintered into a product block. Boron nitride, also known as white graphite, has good electrical insulation, thermal conductivity, excellent thermal shock resistance and chemical stability, and good moisture resistance to molten metal, slag, and glass.

Boron nitride ceramics have the advantages of high-temperature resistance, use temperature of 2000 degrees and alumina does not exceed 1700 degrees. The heat shock resistance is very good, and the boron nitride ceramics will not crack, 1000 degrees of furnace heat out for 20 minutes to blow the air and cold repeatedly hundreds of times will not crack. All sizes can be processed according to the customer's requirements.
Boron nitride is prone to moisture absorption and should not be placed in wet areas when the crucible is unused. Sealed, can not be washed, dirty, and wiped directly with sandpaper.
Hot pressed at high temperature (1900℃).
