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

The BN Ceramic Sleeve<\/strong>\u00a0(also known as the Ceramic Structural Ring<\/strong>) is a high-performance ceramic material made from boron nitride (BN)<\/strong>, offering excellent high-temperature stability, superior electrical insulation, and excellent thermal conductivity. This product is designed to perform in extreme conditions, maintaining structural integrity even at elevated temperatures. BN Ceramic Sleeves<\/strong>\u00a0are widely used in industries requiring high-temperature and high-pressure environments, with a focus on thermal management<\/strong>\u00a0and electrical insulation<\/strong>\u00a0applications. These sleeves are essential components in modern high-precision industrial systems.<\/p>\n

Features<\/strong><\/h3>\n
    \n
  • High-Temperature Stability<\/strong>: The BN ceramic sleeve can withstand temperatures up to 850\u00b0C<\/strong>in air or 2000\u00b0C<\/strong>\u00a0in an inert gas environment, maintaining stability and performance under extreme conditions.<\/li>\n
  • Excellent Electrical Insulation<\/strong>: With a resistivity of up to 10^16 \u03a9\u00b7cm<\/strong>at room temperature, it ensures safety in electrical applications by providing effective insulation.<\/li>\n
  • High Thermal Conductivity<\/strong>: With a thermal conductivity range of 50-70 W\/(m\u00b7K)<\/strong>, it efficiently optimizes heat transfer and helps improve overall device thermal performance.<\/li>\n
  • Low Thermal Expansion<\/strong>: With a coefficient of thermal expansion (CTE) of 1-1.2 x 10^-6\/K<\/strong>, it ensures dimensional stability during thermal cycling.<\/li>\n
  • Chemical Inertness<\/strong>: The boron nitride material exhibits resistance to most chemicals and corrosive environments, ensuring consistent performance.<\/li>\n
  • Self-Lubricating<\/strong>: Due to its hexagonal crystal structure, boron nitride has inherent self-lubricating properties, making it ideal for low-friction mechanical applications.<\/li>\n<\/ul>\n

    Applications<\/strong><\/h3>\n
      \n
    • Semiconductor Manufacturing<\/strong>: Used for handling and positioning silicon wafers during the semiconductor manufacturing process, especially in thermal treatment<\/strong>and wafer fabrication<\/strong>\u00a0stages, providing both thermal management<\/strong>\u00a0and structural support.<\/li>\n
    • Aerospace<\/strong>: Employed in high-temperature components in the aerospace industry, such as engine parts<\/strong>and thermal protection systems<\/strong>, capable of withstanding extreme temperatures and mechanical stresses.<\/li>\n
    • Electronic Devices<\/strong>: Serves as an electrical insulator<\/strong>and thermal interface material<\/strong>\u00a0for high-temperature electronic components, protecting sensitive electronics from heat damage.<\/li>\n
    • High-Temperature Industrial Equipment<\/strong>: Ideal for use in heat treatment furnaces<\/strong>, kilns<\/strong>, and reactors<\/strong>, where it serves as both a structural<\/strong>and insulating<\/strong>\u00a0component, ensuring stable operation in high-temperature environments.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"[tp_attributes num_attributes=\"5\"]\n
