Production Method of AlN Ceramic Microsphere Aluminum Nitride AlN :

Raw material preparation

The production of aluminum nitride ceramic microspheres requires the preparation of the following raw materials:

Aluminum oxide powder: as an essential raw material, it requires high purity, fine particle size, and good activity.

Aluminum nitride powder: as a nitriding source, it requires high purity, fine particle size, and good activity.

Binder: Usually used polymer, resin, etc., used to improve the fluidity of the slurry.

Solvent: Used to adjust the viscosity of the slurry, such as ethanol, acetone, etc.

Catalyst: Used to promote nitriding reaction, commonly used ammonium chloride, sodium nitrate, etc.

Prepare the slurry

The aluminum oxide powder, nitride powder, binder, solvent, and catalyst are mixed according to a particular proportion and are ground or stirred in a ball mill or blender to prepare a uniform and stable slurry. In this process, it is necessary to control the grinding time, starting speed, and viscosity parameters to ensure the performance of the slurry.

Preparation of microsphere morphology

The microsphere morphology was prepared by spray drying, ball milling, or 3D printing. Among them, the spray drying method is to spray the slurry into a mist through the nozzle and form a microsphere shape during the drying process. The ball mill method is to put the slurry into the ball mill for a specific time so that the slurry gradually forms a microsphere shape. The 3D printing method uses 3D printing technology to print the formation of the microsphere directly.

Nitriding treatment

The prepared microspheres were nitrided to obtain aluminum nitride ceramic microspheres. Nitriding is usually treated by high-temperature heat treatment or chemical vapor deposition. Among them, the high-temperature heat treatment puts the microsphere morphology into the nitriding furnace, and heat treatment is carried out by injecting nitrogen at a high temperature. Chemical vapor deposition (CVD) is a process in which the microsphere morphology is put into a deposition furnace, and nitrogen-containing gas is introduced for the chemical reaction to form an aluminum nitride layer on the microsphere's surface.

Post-processing

After nitriding, the resulting aluminum nitride ceramic microspheres must be post-treated to obtain the final product. Post-treatment includes cleaning, drying, surface treatment, etc. Among them, cleaning is to remove impurities and residues attached to the microsphere's surface; Drying is to remove the water and solvent inside the microsphere; surface treatment is to improve the surface smoothness and insulation properties of the microspheres.
