Aluminum Nitride Ceramic Rodsmerits

Aluminum nitride ceramic thin rods are a kind of high thermal conductivity, high insulation precision rod-like structural parts, with the advantages of stable slender size, high straightness, fast heat dissipation and high temperature resistance. Compared with alumina thin rods, its thermal conductivity is more efficient, can quickly take away the local heat, while maintaining excellent electrical insulation properties. The coefficient of thermal expansion is close to that of silicon, which is especially suitable for semiconductor positioning pins, laser guide rods, electronic support rods and automation precision ejector pins and other demanding scenarios.

Applications of Aluminum Nitride Ceramics

Aluminum Nitride (AlN) ceramics have high thermal conductivity and electrical insulation, so they can be used in a variety of electronic devices. Aluminum nitride has a thermal conductivity greater than 170W/(mk), good resistance to thermal shock, and can be used in high temperature environments up to 2200℃. Therefore, aluminum nitride ceramic products are ideal for many industries, such as:

Radiators and heat sinks
Electronics Packaging Substrates
Substrates and insulators for microelectronic and optoelectronic devices
Laser Thermal Management Components
electrical insulation
Molten Metal Fixture

Basic Properties of Aluminum Nitride Ceramics

Aluminum Nitride (AlN) is a covalently bonded compound, atomic crystal, diamond-like nitride, hexagonal crystal system, fibrillated zincite crystal structure, non-toxic, white or off-white.

High thermal conductivity (>170W/m-K), close to BeO and SiC, more than 5 times that of Al2O3;
The coefficient of thermal expansion matches that of Si and GaAs;
Various electrical properties (dielectric constant, dielectric loss, body resistivity, dielectric strength) are excellent;
Good mechanical properties, higher flexural strength than Al2O3 and BeO ceramics, can be sintered at atmospheric pressure;
It can be produced by casting process and is a promising substrate and packaging material for high power integrated circuits.
