Abstract
Metal oxyanion coated substrates are disclosed comprising a three dimensional inorganic porous substrate having a coating of metal oxyanion on at least a portion of all three dimensions thereof, produced by a unique process having particular applicability to the manufacture of metal oxysulfide, oxycarbide and oxynitride coated three dimensional substrates. Certain novel coated substrates, such as diatomite porous substrates are disclosed. The coated substrates are useful in polymers, catalysis, heat dissipation and shielding applications.
Claims20
An article comprising a thermally associated nondeleterious contaminated metal oxyanion coated three dimensional powder particle substrate having an inner porous substrate core and a metal oxyanion coating thermally associated with at least a part of the external surface of said inner core without substantially adversely effecting the solid integrity of the substrate, said metal and anion being chemically different.
An article comprising a thermally associated nondeleterious contaminated metal oxycarbide coated three dimensional powder particle substrate having an inner porous substrate core and a metal oxycarbide coating thermally associated with at least a part of the external surface of said inner core without substantially adversely effecting the solid integrity of the substrate, said metal and carbide being chemically different.
An article comprising a thermally associated nondeleterious contaminated metal oxynitride coated three dimensional powder particle substrate having an inner porous substrate core and a metal oxynitride coating thermally associated with at least a part of the external surface of said inner core without substantially adversely effecting the solid integrity of the substrate, said metal and nitride being chemically different.
