Preparation method for instant firing type high-purity aluminum oxide ceramic substrate
The invention discloses a preparation method for an instant-fired high-purity aluminum oxide ceramic substrate, and belongs to the technical field of precision ceramic production and manufacturing processes. The preparation method for the instant-fired high-purity aluminum oxide ceramic substrate is relatively good in dispersion effect, uniform in volume density and capable of effectively reducing residual stress of green bodies in the production process. The preparation method comprises the following steps: preparing slurry through synchronous circulation double dispersion, preparing a green body through hot press molding, eliminating residual stress in the green body through aging treatment, discharging glue, and sintering to prepare the instant-fired high-purity aluminum oxide ceramic substrate. Wherein when the slurry is prepared by synchronous circulation double dispersion, an ultrasonic dispersion circulation system additionally arranged on mechanical dispersion equipment and the mechanical dispersion equipment are synchronously and circularly operated, and materials added into the mechanical dispersion equipment are subjected to double dispersion to obtain fully dispersed slurry; the prepared instant-fired high-purity aluminum oxide ceramic substrate has the warping degree of less than 0.1 mm, the breaking strength of more than or equal to 550Mpa and the volume density of more than or equal to 3.88 g/cm < 3 >, and is free from cracking and damage.
