I. Performance and Advantages

1. High-temperature resistantBoron nitride substrates offer excellent high-temperature resistance, allowing safe and long-term use up to 1800°C under vacuum, and even up to 2100°C or 2400°C in an atmosphere (specifics vary depending on the product). This feature makes them perform well in high-temperature environments.

2. High thermal shock resistanceBoron nitride substrates exhibit excellent thermal shock resistance during the process of rapid cooling from high temperatures to room temperature. For instance, after being cooled to room temperature from 1000℃ and undergoing 100 cycles, they still do not crack.

3. Low coefficient of thermal expansion, good thermal stabilityBoron nitride sintered plate has a low coefficient of thermal expansion, which means it experiences minimal size change during temperature variations, ensuring excellent thermal stability.

4. Excellent thermal conductivityBoron nitride sintered plate boasts stable thermal conductivity, ensuring the objects fired on it are heated evenly and have a uniform color.

5. Corrosion-resistantBoron nitride substrates maintain stable corrosion resistance at high temperatures and are not easily eroded by chemicals.

6. High strength, high hardnessBoron nitride sintered plates offer high strength and hardness, capable of withstanding significant pressure and wear.
