抄録	In order to clarify the relationship between evaporation of WO₃ and formation of a SiO₂ scale in WSi₂, high temperature oxidation tests of WSi₂ were carried out at the temperature range from 773 to 1773 K in air. The pronounced effect of the evaporation of WO₃ on the structure of oxide scale was found at temperatures higher than 1273 K, and a protective SiO₂ scale was formed above 1573 K. The requisite evaporation rate and the vapor pressure of WO₃ for the formation of a protective SiO₂ scale were estimated to be about 10⁻⁴kgm⁻²s⁻¹ and 10 Pa, respectively.
