The ceramic bars were subjected to single-side grinding experiments on Alumina Ceramics
using diamond abrasives of different particle sizes. The ceramic rod is about 1450 ° C ~ 1600 ° C, the product shrinks sharply, especially between 1450 ° C ~ 1550 ° C, this stage needs to slowly heat up, so that the product has enough time to shrink. The fourth stage: the heat preservation stage, compared with the small size product, the ceramic rod large size product needs a longer holding time, so that the product is fully sintered. The fifth stage: in the cooling stage, due to the creep of alumina in the high temperature stage, the rapid cooling before the creep point will cause stress relaxation of the product.
