Aluminum nitride (AlN) ceramic represents a novel ceramic material renowned for its exceptional comprehensive properties. It boasts a range of outstanding attributes, including remarkable thermal conductivity, reliable electrical insulation, low dielectric constant, and minimal dielectric loss. It is characterized by non-toxicity and thermal expansion compatibility with silicon, rendering it an ideal choice for cutting-edge applications like highly integrated semiconductor substrates and electronic device packaging. With a decomposition temperature reaching up to 2450\u2103 at room temperature, it serves as a versatile material for crucibles, evaporation boats, thermocouple protection tubes, and high-temperature insulating components used in the smelting of non-ferrous metals and semiconductor materials like gallium arsenide. Simultaneously, it finds utility as a high-temperature corrosion-resistant structural ceramic and transparent aluminum nitride ceramic.<\/p>\n

Key Features:<\/p>\n

    \n
  1. Exceptionally high thermal conductivity (up to 170W\/m \u00b7 K), comparable to BeO and SiC, exceeding Al2O3 by more than fivefold.<\/li>\n
  2. Thermal expansion coefficient (4.5 \u00d7 10-6\/\u2103) closely matching Si (3.5-4 \u00d7 10-6\/\u2103) and GaAs (6 \u00d7 10-6\/\u2103).<\/li>\n
  3. Outstanding electrical properties encompassing dielectric constant, dielectric loss, volume resistivity, and dielectric strength.<\/li>\n
  4. Strong mechanical attributes, exhibiting higher bending strength than Al2O3 and BeO ceramics, and amenable to sintering under normal pressure.<\/li>\n
  5. Notable optical transmission characteristics.<\/li>\n
  6. Effective insulation properties and resistance to plasma etching.<\/li>\n<\/ol>\n

    Applications:<\/p>\n

      \n
    1. Aluminum nitride ceramic substrates, featuring high thermal conductivity, low expansion coefficient, strength, high-temperature resilience, chemical resistance, resistivity, and low dielectric loss. These make it an optimal choice for heat dissipation substrates and packaging materials in large-scale integrated circuits.<\/li>\n
    2. Aluminum nitride serves as a novel, high-hardness wear-resistant ceramic material, surpassing traditional aluminum oxide, suitable for parts subjected to severe wear.<\/li>\n
    3. Leveraging AIN ceramics’ heat resistance, melt erosion resistance, and thermal shock resistance, it finds application in crafting GaAs crystal crucibles, Al evaporating dishes, magnetohydrodynamic power generation devices, corrosion-resistant parts for high-temperature turbines, and infrared windows due to its optical properties. AlN thin films are used for high-frequency piezoelectric components, VLSI substrates, and more.<\/li>\n
    4. The heat-resistant, molten metal-corrosion-resistant, and acid-stable nature of aluminum nitride makes it ideal for smelting crucibles for metals like aluminum, copper, silver, lead, and for sintering and casting die materials. When exposed to humid air, a thin oxide film forms on the surface, enhancing its functionality.<\/li>\n<\/ol>\n
