Spherical alumina powder
Compared with other powder particles of different shapes,sphericalThe particle shape is regular, the specific surface area is smaller, the bulk density is higher, and the fluidity is better, which can greatly improve the application performance of the product.
sphericalAlumina is a product obtained by melting random high-purity alumina at high temperature, spraying and sintering, and then sieving and purifying. Alumina has high purity, high spheroidization rate and controllable particle size distribution. The product has excellent properties such as high thermal conductivity, good fluidity, and low oil absorption.

application
1. Thermal Conductive Materials/Thermal Interface Materials/Thermal Plastics/Thermal Clads
It can fill the microscopic gap generated when two materials are combined or contacted, thereby reducing the resistance formed during heat transfer and improving heat dissipation performance. Spherical alumina is a common inorganic filler in thermal interface materials, and its thermal conductivity reaches 30~42W/m·K.

2. Ceramic material
Spherical micropowder has good pressing and sintering properties, which is very conducive to making high-quality ceramic products. Spherical alumina can greatly improve the toughness of ceramics. When the content of spherical alumina powder is 5.0%, it can effectively improve the toughness of ceramics and reduce the sintering temperature.
