PLASMA-RESISTANT COATING FILM, SOL GEL LIQUID FOR FORMING SAID FILM, METHOD FOR FORMING PLASMA-RESISTANT COATING FILM, AND SUBSTRATE WITH PLASMA-RESISTANT COATING FILM
The plasma-resistant coating film according to the present invention is formed on a substrate, including crystalline Y2O3 particles having an average particle diameter of 0.5 µm to 5.0 µm in a SiO2 film, in which a film density of the plasma-resistant coating film is 90% or more, the film density being obtained by performing image analysis of a cross section of the film with an electron scanning microscope and by using the following expression (1), a size of pores in the film is 5 µm or less in terms of diameter, and a peeling rate of the film from the substrate measured by performing a cross-cut test is 5% or less. Filmdensity%=S1−S2/S1×100However, in the expression (1), S1 is an area of the film and S2 is an area of a pore portion in the film.
