The present invention relates to a slurry for suspension plasma spraying containing a dispersion medium and rare earth oxide particles, wherein the rare earth oxide particles have a particle diameter D50 of 1.5 μm to 5 μm, a BET specific surface area of less than 1 m^2/g, and a content of rare earth oxide particles in the slurry of 10 to 45 wt%. The slurry for thermal spraying of the present invention can contribute to stable formation of a spray coating containing a rare earth oxide phase as a main phase. 분산매 및 희토류 산화물 입자를 포함하는 서스펜션 플라즈마 분무용 슬러리이며, 희토류 산화물 입자는 입자 직경 D50이 1.5 μｍ 내지 5 μm이고, BET 비표면적이 1 m2/g 미만이고, 슬러리 중의 희토류 산화물 입자의 함유율이 10 내지 45 wt%이다.
