Preparation of nanomaterials from metalorganic compounds of tungsten and molybdenum.

We have studied the sequence of phase transformations of the thermolysis products of tungsten- and molybdenum-containing metalorganic compounds and examined the influence of various phases on the formation of nanocrystalline carbide materials and the possibility of controlling the particle size of forming phases. We have obtained WC and WC/Co materials ranging in crystallite size from 13 to 26 nm and high-porosity (up to 80%) molybdenum, nickel-molybdenum, and titanium-molybdenum materials ranging in strength from 5 to 26 MPa.
