Boron Nitride Crucible | BN Ceramic

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.

Boron Nitride Crucible Available Materials Types

Boron Nitride Crucible Using Tips

• In order to ensure the service life of the crucible, it is recommended to use it under a protective gas environment (Ar/N2).
• The maximum working temperature in the air is 900℃, the crucible will be oxidized when exceeding 900℃, which will affect its use.
• It is recommended to store the crucible in a dry and sealed container.
• Use fine sandpaper or cloth to remove any dirt or residue from the crucible, do not use water to clean the crucible.
• Not to be used for the treatment of samples such as antimony oxide, chromium oxide, molybdenum trioxide, arsenic trioxide, hard titanium alloy, high-lead glass glaze, boron phosphates, potassium phosphate, chloride, and so on.

Boron Nitride Crucible Available Materials

• Black metal: iron, copper, aluminum, nickel, magnesium, bismuth, zinc, etc., alloy FE-CO-NI-SI CO-ZR-NB.
• No reaction between water and acid at room temperature.
• Rare earth, boron acid, and ammonia.

Boron Nitride Crucible Unavailable Materials

• Melantimony trioxide, chromium seven-oxide, molybdenum trioxide, arsenic trioxide, and titanium carbide.
• Boron phosphate erodes boron nitride in 1400 degrees of nitrogen and will react with hot thick or molten alkali and hot chlorine gas.

Boron Nitride Crucible Applications
