In the field of high-temperature applications, the requirements for material performance are becoming increasingly stringent. Our mini aluminum nitride ceramic crucible, with its exceptional performance, has become an ideal choice for numerous industries. 1、Ultra-High Thermal Conductivity: The mini aluminum nitride ceramic crucible boasts an ultra-high thermal conductivity, ensuring efficient heat transfer. Whether for non-ferrous metal smelting or semiconductor material synthesis, it can distribute heat quickly and evenly, greatly improving process efficiency while reducing energy consumption and supporting sustainable industrial operations. 2、Excellent Thermal Stability: It can withstand extreme high temperatures. As a high-temperature refractory crucible, it still operates stably in harsh environments where other materials are incompetent, ensuring long-term reliable performance, reducing downtime, and improving production efficiency. 3、Superior Chemical Resistance: It has excellent resistance to corrosion, does not react with non-ferrous metals such as copper, aluminum, and silver, and can also resist the dissolution of aluminum, iron, and aluminum alloys. In semiconductor applications, its stability against molten salts like gallium arsenide is particularly crucial, which can prevent silicon contamination and ensure the production of high-purity semiconductor materials.
