Aluminum oxide has the chemical formula Al2O3. It is a white powdery, high-hardness compound with a melting point of 2054 degrees and a boiling point of 2980 degrees. It is an ionic crystal that can be ionized at high temperatures and is often used in refractory materials. Aluminum oxide has the characteristics of porosity, high dispersibility, insulation, stable crystal phase, high hardness, and good dimensional stability.
Spherical Al2O3 powder is a kind of alumina powder material obtained from random high-purity alumina through high-temperature melting spray calcination, and then through sieving and purification processes. The product has the properties of high thermal conductivity, high insulation, high hardness, high temperature resistance, corrosion resistance, and wear resistance. It also has unique and excellent characteristics such as good fluidity, low oil absorption, high spheroidization, high alpha phase content, small specific surface area, and controllable particle size distribution.
Spherical Al2O3 Powder Properties
●High filling
High sphericity rate and controllable particle size distribution, high-density filling of silica gel and epoxy can be carried out to obtain a mixture with low viscosity and good fluidity;
●High thermal conductivity
Because of its spherical appearance, it can achieve multi-directional heat transfer, good dispersion in the system, and high thermal conductivity of thermally conductive products;
●Low wear
Because of its spherical appearance, the abrasion of the mixer, molding machine and other equipment is reduced, and the life of the equipment is prolonged.
Spherical Al2O3 Powder Applications
●Thermal Interface Material
Spherical Al2O3 power used as thermally conductive silicone gasket, thermally conductive silicone grease, thermally conductive potting glue, thermally conductive double-sided adhesive, phase change materials, etc.;
