With the good technology and strong teamwork, Nextgen Advanced Materials supplies high-quality Spherical alumina powder in good packing.
As the professional manufacture, we would like to provide you Nextgen Spherical Alumina Powder. And we will offer you the best after-sale service and timely delivery. Spherical alumina is also called sand alumina, alpha alumina. In the crystal lattice of α-type alumina, oxygen ions are densely packed in hexagons, and AI3+ is symmetrically distributed in the octahedral coordination center surrounded by oxygen ions. The lattice energy is large, so the melting point and boiling point are high.
It has the characteristics of corrosion resistance, wear resistance, high temperature resistance, high strength, good insulation, large surface area, high hardness, and oxidation resistance. So Spherical Alumina powder is a kind of powder with high thermal conductivity, good heat resistance, high electrical insulation, high hardness, and low abrasity. The spherical nature of this powder allows for high flowability and high packing density.
