Thermal oxide powder

Thermally conductive alumina is a white powder crystalline generated under high temperature conditions, its crystalline powder is numerous, used for high thermal conductivity compound powder has spherical alumina, sphere-like alumina, high purity alumina, composite alumina, etc.. Ultra-high thermal conductivity compound powder must have narrow particle size distribution, good particle size stability, high thermal conductivity K value, and high filler content after coupling modification. Generally speaking, if the average particle size of the thermally conductive filler powder can be controlled within a reasonable range, the thermal conductivity can reach between 3-10W/(m*K) according to different filling amounts.
