Overview of 70%Aln+30%Bn Composite Boron Nitride/Aluminum Nitride Ceramics

Aluminum Nitride Ceramic is an advanced ceramic material with aluminum nitride as the main component. It has been widely used in electronics, optics, and mechanics due to its unique properties.

Features of 70%Aln+30%Bn Composite Boron Nitride/Aluminum Nitride Ceramics

High thermal conductivity: Aluminum nitride ceramics have relatively high thermal conductivity, usually between 170-260 W/m·K, which makes it an excellent heat dissipation material. It is especially suitable for electronic devices that require efficient heat dissipation, such as substrate materials for power semiconductor devices.

Good electrical insulation: Despite its high thermal conductivity, aluminum nitride ceramics are excellent insulators of electricity, which can effectively prevent current leakage and ensure the safe operation of electronic components.

Low dielectric constant and dielectric loss: These characteristics make aluminum nitride ceramics very suitable for use in high-frequency circuits because it can reduce energy loss during signal transmission.

High temperature resistance: Aluminum nitride ceramics can maintain structural stability and strength at extremely high temperatures. Its melting point is about 2800°C, so it is suitable for applications in high temperature environments.

Low thermal expansion coefficient: Compared with semiconductor materials such as silicon, aluminum nitride has a lower thermal expansion coefficient, which means it has better dimensional stability when the temperature changes, which helps improve packaging reliability.

Corrosion resistance: Aluminum nitride ceramics have good chemical stability to most molten metals and are not easily oxidized or corroded, allowing them to perform well in harsh environments.

High mechanical strength: Although not as hard as some other types of ceramic materials, aluminum nitride ceramics still provide enough mechanical strength to allow them to be used in many structural applications.

5 FAQs of 70%Aln+30%Bn Composite Boron Nitride/Aluminum Nitride Ceramics

What are 70% AlN + 30% BN ceramics?
These ceramics combine aluminum nitride and boron nitride. They mix 70% aluminum nitride powder with 30% boron nitride powder. Manufacturers press and sinter this mixture under high heat. This process creates a solid ceramic material. This material keeps the best features of both parts.

Why is thermal conductivity important?
These ceramics move heat very well. Aluminum nitride itself moves heat efficiently. Adding boron nitride keeps this ability high. The mix still moves heat much better than many other materials. This is vital for parts needing fast heat removal. Electronics and high-power devices need this.

Do these ceramics conduct electricity?
No, they do not conduct electricity. They are excellent electrical insulators. Both aluminum nitride and boron nitride stop electricity. Combining them keeps this strong insulation property. This makes them safe for electrical uses. They prevent short circuits in electronic parts.

Can you machine these ceramics easily?
Yes, machining is easier than pure aluminum nitride. Pure aluminum nitride is very hard and brittle. It cracks easily when cut. Boron nitride adds lubricity, like graphite. This makes the composite much softer to machine tools. You can cut, drill, and shape it more precisely. This reduces breakage and waste.

How do they handle harsh chemicals?
They resist many chemicals very well. These ceramics won’t react with most acids or alkalis. They also handle molten metals without damage. This chemical stability is strong. It means they last longer in tough environments. Furnace parts and semiconductor tools benefit.
