A method to introduce ceramic particles into liquid metal through the polymeric precursor route by cross-linking organic precursor into a hard polymer, which is added to the liquid melt for in-situ pyrolysis of the organic into the ceramic phase. The starting material, the organic, for the above process can be in the form of a liquid or a solid. If it is a solid it is usually dissolved into a solvent to create a liquid form. The organic is then cross linked either directly by a thermal process, by adding a catalyst, or by the well known sol-gel process into a hard polymer. It is this hard polymer which is then pyrolyzed into a high temperature ceramic material by the process outlined above.
A process for preparation of nano-ceramic metal-matrix composites, said process comprising steps of cross-linking organic precursors to obtain organic polymers, inserting the organic polymers into a metal melt to produce a dispersion of organic polymers within the metal melt;
