PROPERTIES AND APPLICATIONS

Saint-Gobain #222 series ceria stabilized zirconium oxide is a hollow sphere powderdesigned for increased performance in thermal barrier applications. These coatings resistthermal shock, erosion, and corrosion in high temperature applications. This material isespecially suited for applications that aggressively corrode other stabilizers.

The spherical shape produces more uniform build up rates without clogging or pulsing ofthe feed lines. In addition, the hollow particles lead to more complete melting and higherdeposit efficiencies. Crystal phase content is also tightly controlled to minimize theundesirable monoclinic phase of zirconia. Monoclinic zirconia will expand and contractduring thermal cycling and can lead to coating failure.

For higher service temperature applications, Saint-Gobain #204 series 8% yttria stabilizedzirconium oxide (YSZ) may be more appropriate. YSZ is most commonly used for thermalbarrier applications like the hot zones of aircraft or industrial gas turbines.
