Abstract
The present invention discloses a method of making materials and coatings formed from multiple component compositions characterized by improved uniformity, improved dispersion and/or improved homogeneity on the atomic, nanometer, or sub micron scale. These compositions are prepared by forming a mixture of component precursors in the presence of at least one suitable organic reagent and a solvent. Suitable reagents include those in which the sum of the hydroxy and carboxy groups contained in their molecular structure is at least two, which form a rigid, gel-like matrix upon suitable treatment and which decompose completely at high temperatures, leaving no residue. This method is useful for making compositions that are useful in the production of ceramics, supports, catalysts, modified supports, electronics, coatings, films, laminates, superconductors and similar products.
