Preparation method of composite aluminum nitride ceramic substrate
The invention discloses a preparation method of a composite aluminum nitride ceramic substrate. The preparation method comprises the following steps: subjecting raw materials for preparing the composite aluminum nitride ceramic substrate to a raw material ball milling step, a defoaming step, a tape casting step, a punching step, a laminating step, a glue discharging step and a sintering step to obtain a finished product of the composite aluminum nitride ceramic substrate, the raw material ball-milling step comprises the following steps: feeding aluminum nitride powder, heat-conducting powder, a sintering aid, an organic solvent and a dispersing agent into a ball mill for ball-milling treatment; the defoaming step comprises the following steps: vacuumizing and defoaming the materials subjected to the ingredient ball milling step by adopting a vacuum defoaming machine to obtain ceramic slurry; the tape casting step comprises the following steps: feeding the ceramic slurry subjected to the defoaming step into a tape casting machine for tape casting, and standing for a certain time to obtain a green belt; the heat conductivity of the composite aluminum nitride ceramic substrate prepared by the preparation method of the composite aluminum nitride ceramic substrate is between that of aluminum oxide and that of aluminum nitride, and the cost of the composite aluminum nitride ceramic substrate is lower than that of an aluminum nitride ceramic substrate in the prior art.
