A process for producing tin oxide fibers, which comprises forming a melt comprising a solute composed essentially of tin oxide and a solvent selected from the group consisting of copper, a copper alloy, tin or a tin alloy, evaporating the solute from the melt, and introducing the evaporated solute to a low temperature zone, whereby tin oxide fibers are permitted to precipitate and grow in the low temperature zone.
