The properties and applications of high purity spherical aluminum nitride

The high purity spherical aluminum nitride has attracted wide attention from academia and manufacturers at home and abroad for its excellent high thermal conductivity, low dielectric constant, thermal expansion coefficient matching with Si, and other excellent physical and chemical properties, and is known as the new ideal substrate material for a generation of high-density packaging.

The properties of aluminum nitride:

The high purity spherical aluminum nitride is an atomic crystal, belonging to diamond-like nitride, hexagonal crystal system, wurtzite crystal structure, non-toxic, white or off-white. The high purity spherical aluminum nitride is a substance connected by covalent bonds. It has a hexagonal crystal structure, which is the same shape as zinc sulfide and wurtzite.

The high purity spherical aluminum nitride can be stabilized up to 2200℃. Aluminum nitride has good thermal conductivity and low thermal expansion coefficient, making it a good thermal shock material. The high purity spherical aluminum nitride has strong resistance to molten metal corrosion and is an ideal crucible material for casting pure iron, aluminum or aluminum alloy. The high purity spherical aluminum nitride is also an electrical insulator with good dielectric properties.

The applications of aluminum nitride:

The high purity spherical aluminum nitride has a thermal conductivity of 160-230W/mk, and has been widely used in high-power module circuits, switching power supplies, and other high-power devices that require insulation and high heat dissipation, and as a carrier substrate for mobile phone microcircuit chips.

1. The high purity spherical aluminum nitride is used in optoelectronic engineering, including as dielectric layer in optical storage interface and electronic substrate, as chip carrier with high thermal conductivity, and for military use.

2. Due to the characteristics of the piezoelectric effect of high purity spherical aluminum nitride, the epitaxial stretching of aluminum nitride crystals is also used in surface acoustic wave detectors. The detector will be placed on the silicon wafer. There are very few places where these thin films can be reliably manufactured.

3. The use of high purity spherical aluminum nitride has high room temperature and high temperature strength, small expansion coefficient, and good thermal conductivity. It can be used as a heat exchanger material for high-temperature structural parts.

4. Using high purity spherical aluminum nitride can withstand the corrosion properties of metals and alloys such as iron and aluminum, it can be used as a crucible and casting mold material for melting metals such as Al, Cu, Ag, Pb.

And, TRUNNANO provides high purity high purity spherical aluminum nitride with reasonable price. “In order to feedback to old customers, the company is still in full operations to provide high purity spherical aluminum nitride with competitive price.” said Olina, sales manager of TRUNNANO.
