Conducting fine powder was obtained in the Zn-In-O system by combustion of the gel prepared from an aqueous solution of mixed zinc and indium nitrates in the presence of glycine. Glycine worked as a fuel as well as a gelling agent in the combustion under the strong oxidizing power of the nitrates. In spite of the low furnace temperature of 350 deg. C, the product was (ZnO){sub 3}In{sub 2}O{sub 3} which has been obtained above 1260 deg. C in a solid state reaction of a mixture of ZnO and In{sub 2}O{sub 3}. The combustion synthesis led to an aggregated fine powder of hexagonal platelets of about 40 nm in diameter. Its compacted mass showed an electrical resistivity of about 700 {omega} cm. The agglomeration was improved by dispersing the fine powder in an acetic acid aqueous solution.
