Aluminum Nitride Powder is a high-performance ceramic material with excellent thermal and electrical conductivity properties. It is composed of aluminum and nitrogen atoms, forming a hexagonal crystal structure. The powder is produced through various synthesis methods, including chemical vapor deposition and carbothermal reduction.
Aluminum Nitride Powder is known for its exceptional thermal conductivity, which is even higher than that of alumina and many other ceramic materials. This property makes it highly suitable for applications that require efficient heat dissipation, such as electronic components, power devices, and thermal interface materials.
In addition to its thermal conductivity, Aluminum Nitride Powder also exhibits excellent electrical insulation properties, high mechanical strength, and good chemical stability. These characteristics make it a versatile material used in the production of substrates, heat sinks, substrates for integrated circuits, LED packaging, and microwave components.
Furthermore, Aluminum Nitride Powder is often utilized as a filler or additive in composite materials to enhance their thermal conductivity. The powder can be processed into various forms, including coatings, films, ceramics, and molded parts, to meet the specific requirements of different applications.
Overall, Aluminum Nitride Powder is a valuable material in the field of advanced ceramics, offering a unique combination of thermal and electrical properties that make it indispensable in numerous industries.
1. High thermal conductivity (about 10 times that of alumina).
2. Close to the thermal expansion coefficient of silicon.
3. High electrical insulation.
4. High strength (higher than alumina).
5. Corrosion resistance (not wetted on almost all molten metals).
6. High purity (no contamination of molten metal even at high temperature).
7. It has light transmittance (it can pass through visible light ~ infrared ray)
8. It has halogen resistance ionic properties.
1. Molding materials for EMC semiconductor component packaging.
2. MCPCB metal substrate insulation and thermal conductive filling.
3. TIM thermal conductive interface material thermal conductive filling.
4. Filling with potting adhesive / thermal conductive adhesive.
