Products Description
Aluminum nitride ceramic crucibles are containers manufactured by sintering high-purity aluminum nitride powder at elevated temperatures. They are primarily used for material processing in high-temperature, highly corrosive environments, if metal smelting, crystal growth, semiconductor fabrication, and high-temperature chemical analysis. Compared to traditional oxide ceramic crucibles (if alumina or zirconia), its core advantages lie in exceptionally high thermal conductivity, outstanding thermal shock resistance, and excellent chemical inertness toward numerous molten metals (if aluminum, copper, or gallium) and semiconductor materials (if gallium arsenide).
Product performance
-
Bulk density of 3.28–3.32 g/cm³ ensures high density, which guarantees resistance to metal permeation and a long service life.
-
The flexural strength of 300–400 MPa determines the crucible's mechanical load-bearing capacity and resistance to mechanical impact.
-
Thermal conductivity: 150–200 W/(m·K) Core advantage: Enables rapid, uniform heating and cooling while minimizing thermal stress.
Product application
- Semiconductors and Optoelectronics: The preferred crucible material for growing compound semiconductor single crystals like gallium arsenide (GaAs) and indium phosphide (InP). Simultaneously, aluminum nitride ceramic substrates, sealed packages, and optical module ceramic components are widely used in high-power LEDs, lasers, and integrated circuit packaging.
- Electronic Thermal Management: Aluminum nitride ceramic heat sinks, sheets, and gaskets are used to address heat dissipation challenges in high-power devices (e.g., IGBTs, microwave/RF modules), leveraging its superior thermal conductivity over silicon nitride substrates.
- High-Temperature Industrial Components: Aluminum nitride ceramic heating plates, heaters, turbines, and various special-shaped parts are used in semiconductor equipment, high-temperature furnaces, and harsh industrial environments.
- Metal and Material Processing: Beyond crucibles, aluminum nitride plates and ceramic tubes are also used in high-purity metal processing, new material synthesis, sintering, and other fields.
- Special Functional Components: Black aluminum nitride ceramic (typically achieved by adding colorants for specific optical or identification needs) and transparent aluminum nitride ceramic (for optical windows in extreme environments) represent specialized applications.
- Scientific Research and New Energy: Serves as critical consumables in research experiments and finds applications in new energy fields like energy storage batteries. Silicon nitride applications extend to biomedical implants and structural components.
