The Aluminum Nitride ceramic powder produced by Tongrun Tech possesses the characteristics of high purity, small particle size, uniform distribution, high surface activity, low bulk density, and good injection molding properties. It can be used for composite materials and can match with semiconductor silicon. With good interface compatibility, it can improve the mechanical properties and thermal conductivity of dielectric properties of composite materials.
This product should be sealed and stored in dry and cool environment. It should not be long exposed to the air, which causes aggregation and affects the dispersion properties and its performance. Surface treatment could be done according to users¡¯ requirements
High thermal conductivity
All kinds of electrical (dielectric constant, dielectric loss, volume resistivity and dielectric strength)
Good mechanical performance, flexural strength higher than that of Al2O3 and BeO ceramic, can normal pressure sintering
Good optical transmission characteristics
Can use stretch film production process
Good thermal conductivity, thermal expansion coefficient is small, is a good material to heat shock.Of molten metal erosion resistance is strong, is the crucible of the ideal of pure iron, aluminum and aluminum alloy casting materials.Aluminum nitride or electrical insulation, good dielectric properties, used for electrical components are also very promising.Light electrical engineering, including the aluminum nitride in optical storage interface layer induced electric and electronic matrix, in the high thermal conductivity low chip carrier, as well as for military purposes.Due to the characteristics of aluminum nitride piezoelectric effect, the extensionality of aluminum nitride crystal stretch is also used for surface acoustic wave detector.
