Metal non-oxide coated substrates are disclosed comprising a three
dimensional inorganic porous substrate having a coating of metal non-oxide
on at least a portion of all three dimensions thereof, produced by a
unique process having particular applicability to the manufacture of metal
boride, carbide and nitride coated three dimensional substrates. Certain
novel coated substrates, such as diatomite porous substrates are
disclosed. The coated substrates are useful in polymers, catalysis,
heating and shielding applications.
