Aluminum Nitride (AlN)

Aluminum nitride devices have high hardness,high modulus,very high dielectric properties,good oxidation-resistant property and low-thermal expansion efficient,which is approximate to that of Silicon.When the AlN powers is used to make composites its interface compatibleness is good . It can improve mechanical properties,thermal conductance and dielectric properties of composites.

Application --- Nano Aluminum nitride primary used in integrate circuit subtract, electronic devices, optical devices, thermal emission devices,crucibles used at high temperatures,preparation of composites of metal matrixes and polymer matrixes,expecially,in the high temperature seal binders and electronic encapsulation materials,Nano-ALN will be substantially applied in future.

Store --- It  should be storing the cool and dry rooms without solar light 。 The product cannot be in big compression 。 In the use process of Nano-ALN powders, in order to avoid the powder aggregating caused by absorbing moistness and thus affecting application effects,the Nano-ALN powder can be not exposed in air.
