A novel chemical mechanical polishing slurry for yttrium ...

Abstract. Yttrium aluminum garnet (Y3 Al 5 O 12, YAG) crystal is widely used for laser applications. However, due to its high hard and brittle nature, high surface quality and high material removal rate (MRR) are difficult to be achieved. In this study, to solve the problem, a novel CMP slurry was developed, which contains 8 wt% ZrO2 abrasives ...
