Abstract
Proposed is an yttrium-based granular powder for thermal spraying. The yttrium-based granular powder includes at least one yttrium compound powder selected from the group consisting of YO, YOF, YF, YAlO, YAlO, and YAlO, and a silica (SiO) powder. The yttrium-based granular powder is prepared by mixing the yttrium compound powder having a mean grain diameter of 50 nm to 900 nm and the silica powder having a mean grain diameter of 50 nm to 900 nm. The yttrium-based granular powder includes less than 10 wt % of a Y—Si—O mesophase. A thermal spray coating produced using the yttrium-based granular powder can exhibit low porosity, high density, and excellent plasma resistance.
