Spherical Aluminum Nitride AlN powder CAS 24304-00-5

What is Spherical Aluminum Nitride AlN Granule:

Spherical aluminum nitride is prepared by laser flame jet fusion method, and the obtained product has high purity, uniform particle size distribution, clean surface, high sphericity, no residual impurities, easy dispersion, and good compatibility with organisms. Aluminum nitride powder undergoes the second laser melting spherical alloying and has a high thermal conductivity (340W) and heat transfer. 

Spherical aluminum nitride is a kind of inorganic powder of high thermal conductivity materials; because of its high thermal conductivity, good insulation, low dielectric constant, and si materials considerable expansion coefficient, and excellent comprehensive performance, more and more attention, it is widely used in large-scale integrated circuit, high thermal conductivity in the field of electronic substrate, inorganic filler of thermal conductivity, high-performance structure ceramics, and other fields.

With the advent of the 5G era, all kinds of electronic devices are increasingly integrated and more powerful. To improve the heat dissipation performance of various packaging resins used in electronics, the best way is to add inorganic insulation filler with high thermal conductivity into the material, and aluminum nitride is one of the best choices. To improve the filling amount, the powder must be compact and spherical, with the particle size ranging from tens of microns to hundreds of microns, to ensure the compound of the size and particle size to achieve high filling and good fluidity.

How is Spherical Aluminum Nitride AlN Granule Produced? 

The invention relates to a method for preparing high-purity, quasi-spherical aluminum nitride particles, which comprises the following steps:

(1) Wet Al2O3 powder, soluble inorganic salt, and water-soluble organic precursor according to the mass ratio, mix the above raw materials, add water, ball mill, and spray granulation to obtain micron-size spherical particles;

(2) the micron-sized spherical particles are placed in a nitrogen atmosphere for microwave synthesis; the synthesis process is divided into two stages: the first stage uses 0.1 5℃/min heating rate from room temperature to 800 1200℃, heat preservation; The second paragraph: the use of 120 ℃/min rates of heating to 1200 1800℃, heat preservation, containing trace carbon nano aluminum nitride particles.

(3) The nano-sized aluminum nitride particles containing trace carbon were decarbonized in the atmosphere of CO2 to obtain the high-purity, sphere-like nano-sized aluminum nitride particles.
