Heat sintered ZrO_2 ceramic does not react with any acids and bases except HF. It can't be coarsened by the traditional pretreatment process. Through a great deal of experiments, author found a kind of coarsened prescription which can corrode ZrO_2 ceramic, forming many holes and troughs on its surface.

高温烧结后的ZrO_2陶瓷的化学稳定性很高，除HF外不溶于任何酸碱，传统的粗化液对它没有粗化作用，笔者通过大量的实验，找到了ZrO_2陶瓷粗化液的配方，它能在ZrO_2表面腐蚀出大量均匀的微坑和凹槽。
