Abstract
A metal carbide composition and a process for synthesizing metal carbides, through a single step process, wherein oxides of different metals, including, but not limited to Si, Ti, W, Hf, Zr, V, Cr, Ta, B, Nb, Al, Mn, Ni, Fe, Co, and Mo were physically mixed with spherical or filamentateous nano structured carbon, and inductively heated to a certain temperature range (900-1900.degree. C.) where the metal oxide reacts with carbon to form different metal carbides. The process retains the original morphology of the starting carbon precursor in the resultant metal carbides. This method also produces highly crystalline metal nano-carbides. The metal carbide products would have applications in high temperature thermoelectric devices, quantum wells, optoelectronic devices, semi-conductors, body armour, vehicle armour, catalysts, and as discontinuous reinforced agents in metal such as aluminum and other alloys.
