These hollow sphere powders feature 8% stabilized yttria with very uniform chemistry. These products are available in a range of particle sizes to meet specific porosity demands, providing high deposit efficiency for long lasting, high performance thermal barrier coatings.

The spherical shape of the 204 powder means more uniform delivery of the powder without plugging or pulsing of feed lines. The hollow particles yield more complete melting, which further increases deposit efficiency.

Saint-Gobain’s #204 PR is recommended to achieve higher levels of porosity for optimal coating life. Contact your Saint-Gobain Coating Solutions representative to determine the optimal powder formulation for your application.

Saint-Gobain’s yttria zirconia powders offer the highest level of deposit efficiency along with the lowest thermal conductivity to deliver maximum resistance to thermal shock, erosion & corrosion in high-temperature applications. These highly homogenous powders have very low impurity levels, thus reducing sintering. Saint-Gobain offers yttria stabilized zirconia powders in a range of formulations and particle sizes.
