High Thermal Conductivity: Its thermal conductivity is much higher than that of traditional ceramic crucibles such as alumina and zirconia. It conducts heat evenly, transfers heat quickly, reduces local overheating, and protects samples from thermal shock damage.
Thermal conductivity up to 320W/m·K ensures rapid heat dissipation.
Low thermal expansion (4.5×10⁻⁶/°C) matches silicon and gallium arsenide.

2.Superior Mechanical Strength
Excellent Electrical Insulation: It maintains high resistivity at high temperatures, making it suitable for electric heating experiments in environments such as vacuum and inert gases without causing electric leakage or electromagnetic interference.High flexural strength (350 MPa) for durability under extreme conditions.

3.Outstanding Chemical Stability
Its high mechanical strength and bending resistance give it an advantage in some applications requiring high strength and rigidity; it also gives it excellent performance in wear-resistant cutting and wear resistance.Low Thermal Expansion Coefficient and Good Matching: Its thermal expansion coefficient is close to that of semiconductor materials such as silicon and gallium arsenide. It has small deformation during heating and cooling, and is not easy to crack due to thermal stress.

4.Excellent Electrical Insulation
High electrical resistivity and low dielectric loss for sensitive applications.High Chemical Stability: At high temperatures, it does not react with most metals (such as Al, Fe, Cu), semiconductors, glass, ceramics, etc., does not contaminate samples, and is stable to acids (except hydrofluoric acid).Aluminum nitride ceramics are excellent electrical insulating materials suitable for electronic devices and other applications requiring electrical insulation.

5.Good High-Temperature Resistance: It performs well in high temperature environments and maintains its structure and performance. Therefore, it is suitable for high-temperature industrial applications such as stoves, heat treatment equipment, etc.The service temperature can reach above 1800℃ (in vacuum or inert atmosphere), which can meet the needs of high-temperature sintering, smelting, synthesis and other experiments.

6.Aluminum nitride ceramics have good stability to chemicals and solvents, so they are widely used in the chemical industry and laboratory environments.Aluminum nitride ceramics have excellent characteristics of non-magnetic and rust-free, and will not be affected by magnetic fields.

Development Prospects of Aluminum Nitride (AlN)

The relentless trend towards miniaturization, higher power density, and increased performance in electronic devices is driving the urgent need for advanced materials that can efficiently manage heat and provide reliable electrical insulation. Aluminum Nitride (AlN), with its exceptional combination of high thermal conductivity and superior electrical insulation, is perfectly positioned to meet these challenges, ensuring its expansive growth across cutting-edge industries.

In the realm of power electronics, AlN is becoming indispensable. It serves as a key material for substrates and heat sinks in high-power semiconductor modules and LEDs, where its ability to dissipate heat far exceeds that of traditional alumina, enhancing device longevity and performance. The aerospace and defense sectors leverage AlN for its stability in extreme environments, using it in RF/microwave components and avionics systems. Furthermore, the rise of new energy technologies, including electric vehicles (EVs) and photovoltaic systems, creates massive demand for AlN ceramic substrates and crucibles for power conversion and high-purity material processing.

As 5G, IoT, and wide-bandgap semiconductors (like SiC and GaN) become mainstream, the operational frequencies and heat generation of devices will only intensify.Aluminum Nitride, with its proven capabilities and ongoing research into even more cost-effective manufacturing processes, stands as a critical enabler for the next generation of high-performance, reliable, and compact electronic systems. Its future is not just promising; it is fundamental to technological progress.
