Calcia Stabilized Zirconia (CSZ) powder is produced through state of the art electric fusion process followed by crushing, grading operations. More specifically Zirconia stabilized with 5% Calcia finds use in the thermal spray industry. Its formulation aims to create thermal barrier coatings offering thermal insulation, resistance to thermal shock, and protection against hot corrosion and sulfidation in high-temperature environments such as combustion chambers. Calcia moderately stabilizes zirconia, mitigating phase transitions as the coating transits to temperature-sensitive zones. Consequently, the coatings exhibit reduced susceptibility to dimensional changes.
