Abstract:
A method of manufacturing a high emittance glass coating which has a glass structure in that pigment particles having a predetermined degree emissivity are dispersed, and which is provided on a surface of a specific structural body, said method including a paste preparation step of preparing a paste which includes said pigment particles and a specific glass powder, a paste coating step of applying said paste to said surface of said specific structural body, and a heat treatment step of forming said glass structure from said glass powder by heating said paste which has been applied to said surface, said method comprising:a pigment-particle covering step of providing on surface of each of said pigment particles a pigment covering film having a predetermined thickness, said pigment covering film including silicon dioxide such that a content of said silicon dioxide in said pigment covering film is higher than a content of said silicon dioxide in each portion of said glass structure which is adjacent to a corresponding one of said pigment particles, said pigment-particle covering step being implemented prior to said paste preparation step, wherein said pigment-particle covering step includes: an inorganic-high-molecular-weight-film forming step of forming an inorganic high molecular weight film on said surface of said each of said pigment particles, said inorganic high molecular weight film being constituted by a high weight inorganic molecule which includes silicon, and wherein perhydropolysilazane is used as said high weight inorganic molecule in said inorganic-high-molecular-weight-film forming step.
