Abstract
Multilayered metal oxide coated substrates are disclosed comprising a three dimensional inorganic substrate having a coating of metal oxide 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 polymers, catalysis, heating and shielding applications.
Claims30
An article comprising a multilayered three dimensional inorganic particle substrate having external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate and having an inner core, a thermally melted and resolidified external barrier surface derived from a part of said inner core and a metal oxide coating thermally associated with said resolidified surface, said resolidified surface and metal oxide coating being on at least a portion of said same external and shielded surfaces and formed at the thermal melting conditions of the inner core surface.
An article comprising a multilayered three dimensional inorganic particle substrate having external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate and having an inner core, a thermally melted and resolidified external barrier surface derived from a part of said inner core and a metal oxide interactant coating thermally associated with said resolidified surface, said resolidified surface and metal oxide coating being on at least a portion of said same external and shielded surfaces and formed at the thermal melting conditions of the inner core surface.
An article comprising a multilayered three dimensional inorganic particle substrate having external surfaces and shielded surfaces which are at least partially shielded by other portions of said substrate and having an inner core, a thermally melted and resolidified poly crystalline external barrier surface derived from a part of said inner core and a metal oxide interactant coating thermally associated with said resolidified surface, said resolidified surface and metal oxide coating being on at least a portion of said same external and shielded surfaces and formed at the thermal melting conditions of the inner core surface.
