Corrosion resistant CMZP and Mg-Al2TiO5coatings for SiC ceramics
Thin film coatings of (Cao.6Mg0.4)Zr4(P04)6 (CMZP) and Mg stabilized AhTiOs ( Mg-Ah Ti05 ) on dense SiC substrates were investigated using sol-gel coating techniques. The thickness and quality of both CMZP and Mg-Ah Ti05 coatings were found to depend on the solution concentration and lift rate. …

The development and characterization of lightweight (CA,MG) ceramics
Lightweight (Ca,Mg)Zr₄(PO₄)₆(CMZP) ceramics have been fabricated with relative densities (P<sub>lightweight</sub>/p<sub>dense</sub>) of less than 0.35 by the polymer foam technique, and higher than 0.35 by the polymer powder technique. The polymer powder method forms an inhomogeneous pore structure …
