1. A process for thermally spraying metal oxide coated ceramic particles onto a substrate comprising:
(I) obtaining a plurality of particles selected from the group consisting only of silicon carbide, silicon nitride, boron carbide or boron nitride, wherein said particles having a continuous coating consisting only of yttrium aluminum garnet; and
(ii) thermally spraying the particles of step (I) onto a substrate, wherein the yttrium aluminum garnet coating forms at least 20 wt % of the coated particle weight before the thermal spraying process.
