Abstract
A method of forming a plasma-resistant coating layer with low brightness includes: (a) performing a heat treatment process on a primary rare-earth metal compound powder having a grain size in a range of 20 nm to 60 nm to prepare a secondary rare-earth metal compound powder, (b) transferring the secondary rare-earth metal compound powder, and (c) spraying the transferred secondary rare-earth metal compound powder onto a substrate to form a rare-earth metal compound coating layer on the substrate. In the transferring transfer, a carrier gas is used to transfer the secondary rare-earth metal compound powder. The secondary rare-earth metal compound powder obtained through the heat treatment process has a grain size in a range of 70 nm to 150 nm, and the rare-earth metal compound coating layer has a brightness value of 50 or less.
