Steel sheet coating compositions in which polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an aluminum resin, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and optionally a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit surface formation of iron oxides and to improve steel sheet surface characteristics.

A method for making a ceramic body comprised of a ceramic material having an inhibitory effect on bacterial growth is provided. A dental prosthesis may be made of a ceramic material that comprises a molybdenum-containing component on a portion of the prosthesis that contacts the gingival surface of a patient. In one method, a porous zirconia ceramic structure is shaped in the form of a dental prosthesis, and then infiltrated with a molybdenum-containing composition, before sintering to densify the ceramic structure.

A composition comprising a carbosilane polymer formed from at least one carbosilane monomer and at least one carbonyl contributing monomer. In some embodiments, the composition is suitable as gap filling and planarizing material, and may optionally include at least one chromophore for photolithography applications.
