Feature

Low monoclinic phase, excellent fluidity, chemical homogeneity and structural integrity. Spayed coating has high porosity.

Spherical shape made from HOSP process. Low monoclinic phase, excellent chemical homogeneity and structural integrity.

Spherical shape, high purity, high monoclinic phase, but will stabilize again during the spraying process.

Applications

Especially suitable for long-term repeated thermal shock environments, such as sintering plates, ladles, and high-end MLCC capacitor material sintering crucible coatings

Particularly suitable for severe and prolonged thermal shock environments, with extremely long coating life. Mainly used for coating aviation turbine blades and heavy-duty gas turbine blades. Under thermal shock erosion in the core high-temperature zone (1200 ° C) of heavy-duty gas turbine blades, the lifespan exceeds - years.

Suitable for thermal protection coatings of standard porosity (4-12 volume percent) turbine thermal components or other parts, with a maximum operating temperature of up to 1350 ° C
