Technical Specifications

Boron Nitride Material Properties

Boron Nitride Ring Advantages

• Low wettability to molten metal
• Relatively high thermal conductivity with low thermal expansion
• Relatively high thermal shock resistance
• Extremely high working temperature with proper inert gas protection (> 3000°C has been recorded.)

Boron Nitride Ring Applications

The boron nitride ring has been widely used as a horizontal continuous-casting separation ring for molten steel. Boron Nitride(BN), Hexagonal boron nitride (H-BN), and hot-pressed boron nitride are good self-lubricated ceramics that can withstand high temperatures and maintain their lubricating capability in a high vacuum environment.  Hexagonal boron nitride (H-BN) behaves similarly to graphite mechanically but offers excellent electrical resistance.

Boron Nitride ceramics from Heeger Materials can bear high temperatures in a high vacuum environment, plus it has excellent corrosion resistance and electrical resistance. Thus, Boron Nitride ceramic product is an ideal choice in a variety of industries, such as:

• Linked undergraduate level
• Lead plate with side sealing plate
• Amorphous, nanocrystalline with a see-through screen
• Special metal cathode and draft tube
