Boron Nitride Crucibles are customized to customer requirements after hot-pressing and sintering boron nitride powder into blocks.
Boron nitride ceramics excel in high-temperature resistance, with a usage temperature of 2000 ℃ compared to alumina's 1700 ℃. They boast exceptional heat shock resistance, remaining crack-free after exposure to 1000 ℃ of furnace heat and repeated cooling cycles.
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.
