Filed: 1989-06-07
Abstract: PURPOSE:To suppress a dicoloring owing to a long period service or an overheating by adding an adequate amount of oxides of iron, nickel, and cobolt to an alumina-titania type ceramics. CONSTITUTION:In an extreme infrared-ray emitting body 5 to which an alumina- titania type ceramics is plasma-spray-coated, FeO, Fe2O3, CaO, and Cr2O3 added to the blackish alumina-titania to be the main component of the spray-coating are the components to have a high effect to suppress a dicoloring. However, since the color of the spray-coating material is changed to a light brown color by adding only such oxides, NiO and CoO are mixed and added complexly. The NiO increases the black color of the membrane, and the CoO increases and maintains the black color. Furthermore, the NiO, SiO2, and Cr2O3 improve the radiation efficiency. And, when the adding ratio of each oxide exceeds 7wt.%, or the total adding amount exceeds 20wt.%, in the adding level of the oxide components, the high-temperature removal-resisting property of the spray- coating membrane is reduced, and the addition shall be made within such a scope, accordingly.
