| Nominal Chemistry | Morphology | Product No. | Nominal Size | Properties & Applications |
|---|---|---|---|---|
| ZrO2, 8%Y2O3 | Hollow Sphere | #204 #204PR #204F |
25-95 µm 44-100 µm 10-45 µm |
|
| - Round and hollow for complete melting and high deposition efficiency - Resists thermal shock, erosion and corrosion in high temperatures - Used as a thermal barrier coating in aircraft and industrial gas turbines - 20YSZ provides lower thermal conductivity but lower erosion resistance than 8YSZ |
