Abstract
The present disclosure relates to an yttrium-based granular powder for thermal spraying. More particularly, the yttrium-based granular powder is a mixture including one or more yttrium compound powders selected from among Y2O3, YOF, YF3, Y4Al2O9, Y3Al5O12, and YAlO3, and a silica (SiO) powder. A Y—Si—O intermediate phase is included therein in a content of less than 10 wt %. The thermal spray coating manufactured using the same has a low porosity, and forms a very dense thin film, thus ensuring excellent plasma resistance.
