## Abstract

A method of producing a composite material comprising: supplying a metal compound (MPC) of a product metal (MP) and a reductant (R) capable of reducing the metal compound (MPC) of the product metal (MP) to a reactor; forming a composite material comprising a matrix of oxidised reductant (R0) of the reductant (R), the product metal (MP) dispersed in the matrix of oxidised reductant (R0), and at least one of (i) one or more metal compounds (MPCR) of the metal compound (MPC) in one or more oxidation states and (ii) the reductant (R); and recovering the composite material from the reactor, wherein the metal compound (MPC) of the product metal (MP) is fed to the reactor such that it is in excess relative to the reductant (R).

## Claims

### Claim 1

A solid composite material comprising:
a matrix of oxidised reductant (Ro), wherein said oxidised reductant (Ro) comprises a metal halide (MRX) selected from the group consisting of MgCl2, NaCl, KCl, LiCl, BaCl2, CaCl2, BeCl2, AlCl3 and any combination thereof;
a product metal (MP) dispersed in said matrix of oxidised reductant (Ro); and
(i) one or more metal compounds (MPCR) of said product metal (MP) in one or more oxidation states, and optionally (ii) a reductant (R);
wherein said one or more metal compounds (MPCR) of said product metal (MP) in one or more oxidation states comprise one or more metal halides (MPX) of said metal component (MP);
wherein said product metal (MP) is selected from the group consisting of titanium, aluminium, vanadium, chromium, niobium, molybdenum, zirconium, silicon, boron, tin, hafnium, yttrium, iron, copper, nickel, bismuth, manganese, palladium, tungsten, cadmium, zinc, silver, cobalt, tantalum, scandium, ruthenium and the rare earths or a combination of any two or more thereof.

### Claim 2 (depends on 1)

A solid composite material according to claim 1, wherein said solid composite material comprises up to 20 wt % of said reductant (R).

### Claim 3 (depends on 1)

A solid composite material according to claim 1, wherein said product metal (MP) comprises at least two of titanium, aluminium and vanadium.

### Claim 4 (depends on 1)

A solid composite material according to claim 1, wherein said reductant (R) is selected from the group consisting of Mg, Na, K, Li, Ba, Ca, Be, Al and any combination thereof.

### Claim 5 (depends on 1)

A solid composite material according to claim 1, wherein said composite material is in the form of particles having an average particle size of up to 500 μm.

### Claim 6 (depends on 5)

The solid composite material according to claim 5, wherein said composite material is in the form of particles having an average particle size of from 20-300 μm.
