Properties:<\/span><\/h2>\n

High Purity (\u2265 99%):<\/strong> High-purity aluminum nitride powder is critical for advanced applications, ensuring minimal contamination in end products, especially in electronics and ceramics.<\/p>\n

High Thermal Conductivity:<\/strong> Aluminum nitride (AlN) has thermal conductivity in the range of 170-200 W\/m\u00b7K, one of the highest among ceramic materials, making it ideal for heat dissipation in electronic applications.<\/p>\n

Electrical Insulation:<\/strong> With excellent dielectric properties, AlN is widely used as an electrical insulator, particularly in applications that also require thermal management.<\/p>\n

Fine Particle Size:<\/strong> Aluminum nitride powder is typically available in micron or submicron sizes, enabling uniform dispersion in ceramic and composite materials for consistent thermal and mechanical properties.<\/p>\n

Stability in High Temperatures:<\/strong> Aluminum nitride (AlN) is stable up to high temperatures (up to about 1000\u00b0C in air) and can withstand thermal cycling without degrading, making it suitable for high-temperature applications.<\/p>\n

Resistance to Corrosion:<\/strong> While generally resistant to most chemicals, AlN can react with moisture, so it\u2019s best stored in dry conditions.<\/p>\n

Applications of Aluminum Nitride Powder<\/span><\/h2>\n

Thermal Management:<\/strong> Aluminum Nitride powder is commonly used in electronic components and substrates where heat dissipation is critical, such as in high-power LEDs, transistors, and other semiconductors.<\/p>\n

Ceramics and Composite Materials:<\/strong> AlN powder is used as an additive in ceramic formulations to enhance thermal conductivity and mechanical strength, creating durable, heat-resistant materials.<\/p>\n

Thermal Interface Materials (TIMs)<\/strong>: Aluminum nitride powder is incorporated into TIMs such as pastes, adhesives, and gels, where it provides effective heat transfer between components and cooling mechanisms.<\/p>\n

Electrical Insulation Materials:<\/strong> AlN\u2019s insulating properties are leveraged in high-voltage and high-frequency components, as well as in components requiring isolation from conductive materials.<\/p>\n

Metal Matrix Composites (MMCs):<\/strong> Aluminum nitride powder is used in metal composites, particularly in aluminum alloys, to improve thermal performance while maintaining electrical insulation.<\/p>\n

Handling and Storage:<\/span><\/h2>\n

Moisture Sensitivity: Aluminum nitride (AlN) can hydrolyze in humid environments, so it should be stored in airtight, dry conditions, often with desiccants, to maintain its quality.<\/p>\n

Proper PPE: Aluminum nitride powder should be handled with care, using protective equipment to avoid inhalation of fine particles.<\/p>\n

FAQs<\/span><\/h2>\n

Q1: What is aluminum nitride\uff1f<\/strong><\/p>\n

A: Aluminum nitride (AlN) is a diamond-like nitride composed of covalent bonds, belonging to the hexagonal wurtzite crystal system. This material is non-toxic, white or grayish-white powder, stable up to 2200\u2103, and has high thermal conductivity (320 W\/m\u00b7K) and a low coefficient of thermal expansion, making it suitable for thermal shock resistant materials, molten metal crucibles, and electronic component substrates.<\/p>\n

Q2: What is the lead time for aluminum nitride powder?<\/strong><\/p>\n

A:\u00a0In-stock items: Available for immediate shipment<\/p>\n

Standard products: Typically 2\u20134 weeks<\/p>\n

Customized products: Lead time will be determined based on your specific requirements<\/p>\n

Special requirements: Please contact us to discuss further details and timelines<\/p>\n

Q3: What is aluminum nitride powder used for?<\/strong><\/p>\n

A: Aluminum nitride powder is widely used in thermal management and electrical insulation applications due to its high thermal conductivity and excellent insulating properties. It is commonly applied in electronic substrates, high-power LEDs, semiconductors, thermal interface materials (TIMs), ceramic and composite materials, and metal matrix composites to improve heat dissipation, strength, and reliability.<\/p>\n

Q4: Can I request a sample of aluminum nitride powder?<\/strong><\/p>\n

A: Yes, we can provide aluminum nitride powder samples for testing and evaluation. Please let us<\/a><\/span> know your required specifications, dimensions, purity, or intended application, and we will arrange the samples for you as soon as possible.<\/p>\n","protected":false},"excerpt":{"rendered":"
