Ceramic powder and powder preparation method of ceramic sheet substrate
The invention belongs to the technical field of waste ceramic sheet recycling, and discloses a ceramic sheet substrate powdering method, which comprises the following steps: sintering a ceramic sheet substrate waste material for at least three times to obtain an intermediate, crushing and ball-milling the prepared intermediate, mixing with a solvent and a dispersing agent, and sanding to obtain slurry, carrying out spray granulation on the prepared slurry to obtain ceramic powder; in the sintering process of intermediate preparation, the sintering temperature is 800-1400 DEG C, and the sintering time is 1.5-3 h. According to the preparation method, the ceramic sheet is sintered, so that unit cells of the ceramic sheet continuously grow in a high-temperature state, the number of grain boundaries of the ceramic sheet is further reduced, the brittleness of the ceramic sheet is increased, the ceramic sheet is easier to grind, and in addition, the preparation method has the advantages that the preparation process is simple, and the preparation cost is low. The invention also discloses the ceramic powder prepared by using the powder preparation method of the ceramic sheet substrate.
本申请属于陶瓷废片返用技术领域，公开了一种陶瓷薄片基板的制粉方法，先对陶瓷薄片基板废料进行至少三次烧结，得到中间体，再将制得的中间体破碎、球磨后与溶剂、分散剂混合并砂磨，得到浆料，随后将制得的浆料喷雾造粒得到陶瓷粉体；在中间体制备的烧结过程中，烧结温度为800～1400℃，时间为1.5～3h，本申请通过对陶瓷薄片的烧结，使得陶瓷薄片的晶胞在高温状态下持续生长，进而减少陶瓷薄片的晶界数量，从而使陶瓷薄片的脆性增大，使其更加易于研磨，此外，本申请还公开了使用上述陶瓷薄片基板的制粉方法制得的陶瓷粉体。
