3. Key Performance Advantages

Strong Adaptability to Extreme Temperatures: Withstands high temperatures up to 2200℃ in inert atmospheres. Combined with its low thermal expansion coefficient, it can stably resist sudden temperature changes, significantly reducing the risk of material failure during experiments.

Excellent Chemical Inertness: Exhibits good corrosion resistance to most molten metals, acidic/alkaline media, making it suitable for container use in harsh reaction systems.

Good Synergy of Functional Properties: The combination of high thermal conductivity and ultra-high resistivity enables it to simultaneously meet the dual needs of “high-temperature thermal management” and “electrical insulation isolation” in scientific research scenarios.

4. Usage Precautions

The operating temperature in air atmosphere must be strictly controlled below 900℃. Overheating will cause BN to oxidize and form B₂O₃, which in turn affects material performance and experimental accuracy.

Diamond-specific tools must be used for mechanical processing to avoid surface damage or structural destruction caused by regular cutting methods.

For long-term storage, the product should be placed in a dry and sealed environment to prevent absorption of moisture in the air, which may affect the purity control of high-temperature experiments.
