Multilayered metal oxide coated substrates are disclosed comprising a three
dimensional inorganic substrate having a coating of metal oxide and a
thermally associated barrier coating on at least a portion of all three
dimensions thereof, produced by a unique process having particular
applicability to the manufacture of tin oxide coated three dimensional
substrates. Certain novel coated substrates, such as flakes, spheres and
porous substrates are disclosed. The coated substrates are useful in
polymer, catalysis, heating and shielding applications.
