Ball milling preparation method for high-uniformity YAG transparent ceramic powder
The invention relates to a ball milling preparation method for YAG transparent ceramic powder used in a procedure of preparation for a YAG transparent ceramic, and belongs to the technical field of transparent ceramic preparation. The method comprises four key detailed processes of ball milling, shaking, sieving and secondary ball milling on slurry. Compared with a common ball milling preparation method, in which only one conventional ball milling procedure is carried out, for the YAG transparent ceramic powder, the delicate and high-operability ball milling preparation method provided by the invention is added with the step of shaking of a ball milling tank up and down in the preparation process, so that raw material powder deposited at the upper part of the ball milling tank can be shaken and sufficiently mixed through ball milling in the subsequent ball milling process; the sieving step is added, so that raw material agglomerated hard particles which are hard to be broken through ball milling can be effectively removed; the ball milling preparation method provided by the invention is further added with the step of secondary ball milling on the slurry, so that the raw material powder can be fully broken and mixed again, and adverse effects on powder uniformity caused by powder deposited at a joint of the ball milling tank and a ball milling tank lid as well as powder deposited at the top of the ball milling tank can be reduced.
