Product Overview<\/strong><\/h3>\n

Pyrolytic Boron Nitride (PBN)<\/strong>\u00a0is a high-performance, specialty ceramic material produced through a unique pyrolytic deposition process. This process deposits hexagonal boron nitride “snowflakes” layer by layer on a substrate, creating products with exceptional high-temperature stability, excellent electrical insulation, and superior corrosion resistance. PBN is widely used in high-temperature, high-pressure, and corrosive environments, particularly in the semiconductor, metallurgy, and high-temperature vacuum industries.<\/p>\n

Features<\/strong><\/h3>\n
    \n
  • High Purity<\/strong>: With a purity level of 99.99%, PBN ensures superior performance and reliability.<\/li>\n
  • Exceptional High-Temperature Performance<\/strong>: Maintains strength up to 2200\u00b0C, providing remarkable thermal stability.<\/li>\n
  • Corrosion Resistance<\/strong>: Resistant to acids, bases, salts, and organic reagents, with no reaction with metals or semiconductors at high temperatures.<\/li>\n
  • Outstanding Thermal Properties<\/strong>: Excellent thermal shock resistance, low thermal expansion, and high thermal conductivity.<\/li>\n
  • Electrical Performance<\/strong>: High electrical resistance, low dielectric constant, and minimal magnetic loss tangent. It also offers excellent microwave and infrared transmission properties.<\/li>\n
  • Anisotropic Characteristics<\/strong>: Displays significant anisotropy in mechanical, thermal, and electrical properties, making it ideal for demanding applications.<\/li>\n<\/ul>\n

    Applications<\/strong><\/h3>\n
      \n
    • Semiconductor Industry<\/strong>: Used for single crystal synthesis crucibles for III-V compounds like GaAs, InP, GaP, and more.<\/li>\n
    • Molecular Beam Epitaxy (MBE)<\/strong>: Ideal for MBE crucibles and boats, supporting precise thin-film deposition.<\/li>\n
    • High-Temperature Vacuum Applications<\/strong>: Employed in high-temperature vacuum furnaces as insulation components.<\/li>\n
    • Graphite Heaters<\/strong>: Used as insulation coatings for graphite heaters to enhance thermal efficiency.<\/li>\n
    • High-Temperature Insulation<\/strong>: Utilized in high-temperature environments for nozzle insulation and MOCVD insulation plates.<\/li>\n
    • Metallurgy<\/strong>: Suitable for specialty crucibles and graphite coating applications in the metallurgical industry.<\/li>\n<\/ul>\n
