Boron nitride ceramic plates, commonly referred to as BN ceramic plates, are used in electric furnaces and other high-temperature applications where excellent thermal conductivity, electrical insulation, and resistance to extreme temperatures are required. They are excellent electrical insulators, ensuring that they do not conduct electricity, making them suitable for applications that require electrical insulation in high-temperature environments.
Applications:
1. Aerospace: They find application in aerospace components, including nozzles and rocket thrust chambers, due to their resistance to high temperatures and wear.
2. Laboratory Equipment: They are employed in high-temperature laboratory furnaces and ovens for scientific research and materials testing.
3. Chemical and Metallurgical Industries: They are used in equipment for the processing of corrosive chemicals and molten metals due to their chemical resistance.
4. Optoelectronics: In the manufacturing of optoelectronic devices, BN ceramics are used for their electrical insulation and thermal properties.
5. Semiconductor Processing: They are used in high-temperature semiconductor processing equipment, such as diffusion furnaces, where electrical insulation, high thermal conductivity, and chemical resistance are essential.
6. Molten Metal Handling: They are used in applications involving molten metals, such as crucibles and containers, because of their high-temperature stability.
7. Electric Furnaces: They are used as heating elements or insulating components in electric furnaces, ensuring efficient heat transfer and temperature uniformity.
8. Dielectric Insulators: In high-frequency and microwave applications, BN ceramics serve as dielectric insulators due to their excellent electrical insulation properties.
