Abstract
Abstract A solution containing at least two metals comprising (a) at least one member selected from the group consisting of a metal alkoxide and an oligomer thereof, and (b) at least one member selected from the group consisting of a metal chelate and a chelating agent. By decomposing the solution, there is provided an inorganic composite material and a multilayer film which are useful as novel functional ceramic materials such as various sensors, electric conductive materials, magnetic recording materials, piezoelectric materials, dielectric materials and materials for optical devices.
