Al 2 O 3 ‐stabilized tetragonal ZrO 2 nanoparticles were obtained through hot‐air spray pyrolysis and characterized after postsynthesized treatments. The produced nanoparticles were 26 nm in size with surface area of 59 m 2 /g. A multilayer thermal barrier coating of nanostructured Al 2 O 3 ‐ZrO 2 ‐embedded silicate was applied to the mild steel ( EN 3) specimen using spin‐coating technique and characterized comprehensively employing X‐ray diffraction and scanning electron microscope. The Al 2 O 3 ‐stabilized ZrO 2 with silicate matrix facilitates the formation of zirconium silicate nanostructured surface‐protective coating on EN 3 specimen. The Al 2 O 3 ‐ZrO 2 /SiO 2 matrix‐based hybrid inorganic coating shows effective thermal barrier for EN 3 after firing at a high temperature of 600°C.
