Aluminum Nitride ceramic sheets AlN Aluminum nitride ceramic heat sinks Heat dissipation substrates Ceramic heat insulation pad

Aluminum nitride (AlN) ceramic substrate is a high-performance ceramic material with aluminum nitride as the main component, which is prepared by powder metallurgy, hot pressing and sintering. It has high thermal conductivity, excellent electrical insulation, good mechanical properties and chemical stability. It is widely used in electronics, semiconductors, aerospace and other fields. It is a key material in modern electronic packaging and heat dissipation technology.

Aluminum nitride (AlN) ceramic substrates are a high-performance electronic material that is widely used in high-power electronic devices due to their excellent thermal conductivity and insulation.

Material properties of aluminum nitride ceramic substrates

· High thermal conductivity: The thermal conductivity is about 170-200 W/m·K, far exceeding that of aluminum oxide (Al₂O₃, about 24 W/m·K), close to metallic aluminum, mainly relying on phonon conduction, and the integrity and purity of the lattice structure are the key.

· Low thermal expansion coefficient: close to semiconductor materials such as silicon (Si) and gallium arsenide (GaAs) (4.5×10⁻⁶/K), reducing device failure caused by thermal stress.

· Excellent insulation: Resistivity>10¹⁴ Ω·cm, suitable for high voltage environments.

· Mechanical properties: flexural strength 300-400 MPa, high hardness but high brittleness, processing requires caution.

· Chemical stability: resistant to high temperature and corrosion, but hydrolysis may occur in a humid environment (surface coating protection is required).

Compared with ceramic substrates of other materials

Characteristics	AlN	Al₂O₃	Si₃N₄
Thermal conductivity (W/m·K)	170-200	24	30-90
Coefficient of thermal expansion (×10⁻⁶/K)	4.5	7.2	3.0
Flexural strength (MPa)	300-400	300-400	700-1000
Cost	High	Low	Medium High

The preparation of aluminum nitride ceramic sheets usually includes the following steps:

1. Powder preparation: Select high-purity aluminum nitride powder and refine it to micron level by ball milling and other methods.

2. Molding: Use dry pressing, injection molding or tape casting technology to press the powder into the desired shape.

3. Sintering: Pressureless or hot pressing sintering is performed at high temperature (1600-2000℃), and sintering aids such as Y₂O₃ are added to reduce the sintering temperature.

4. Post-processing: Improve surface flatness and performance through polishing, coating and other processes.

Application areas of aluminum nitride ceramic substrates

· Power electronics: heat dissipation substrates for IGBT modules and inverters for new energy vehicles.

· LEDs and lasers: heat dissipation solutions for high-brightness LEDs and semiconductor lasers.

· 5G communications: substrate materials for high-frequency RF devices and microwave components.

· Aerospace: high-temperature and radiation-resistant electronic packaging.

Ceramic heat insulation board has excellent heat insulation performance, better than other materials.Insulation performance can be well applied to electronic products, such as circuit boards, processors, components, etc.

Some sizes of ceramic heat insultation pad:

Length	Width	Thickness	Length	Width	Thickness
