amultifunctional material, strontium zirconate, SrZrO3, studied in literatures as a dielectric ceramics, thermal barrier coating, protonconductor, and luminescent material was sprayed by a water-stabilized plasma torch WSP 500. Stainless steel and plain carbon steel were used as substrates. Coatings with thickness of 1 to 2 mm were produced, whereas the substrates were preheated over 450 ° C. The torch working at 150 kW was able to spray SrZrO3 with a spray rate of 10 kg per hour. Microstructure, phase composition, dielectric properties, and optical band gap were also investigated. Prog.
