[0002] With the increasing attention to the research of non-oxide ceramic materials, aluminum nitride ceramics have become a new generation of circuit board packaging materials in the microelectronics industry due to their high thermal conductivity, thermal expansion coefficient matching with silicon, high specific strength, low density, non-toxicity and other advantages. Since it meets the requirements of the rapid development of new generation information materials, significant progress has been made in recent years.

[0003] Aluminum nitride (AIN) is a covalent bond compound, and its crystal structure is hexagonal and cubic. Among them, the cubic crystal form can only be prepared under ultra-high pressure and thin film growth conditions. Common AIN ceramics are all in the hexagonal wurtzite structure. The theoretical density is 3.26 g / cm3, the Mohs hardness is 7-8, and the decomposition temperature is 2200-2250 °C. Aluminum nitride powder is white or grayish white. The density of aluminum nitride products is related to the type and addition amount of selected additives and the preparation process.

[0004] In the preparation process of doped aluminum nitride composite ceramic green bodies, the slurry is prepared by adding organic solvents into a container, gradually adding all binders, aluminum nitride powder, sintering aids, and stirring agents, maintaining the stirring speed and stirring for a certain time, then adding the remaining organic solvents, anti-settling agents and plasticizers, and then high-speed stirring to obtain the slurry; then the slurry is transferred to a sand mill for sanding, and the sanding is cycled until the required fineness is reached. At present, the existing slurry stirring equipment has a relatively single function, and after the ceramic slurry is stirred, there will still be a lot of tiny bubbles, which takes several hours to eliminate, consuming a lot of time.
