Title: A method of a self-supporting block of a ceramic composite production and a self-supporting block of a ceramic composite
IPC: C04B35/65
Filed: 1987-08-07
Abstract: A method for producing a self-supporting ceramic composite body having a negative pattern which inversely replicates the positive pattern of a parent metal precursor (2) having thereon a positive pattern section (4,6,8,9) which is emplaced in conforming engagement with a bed of conformable filler (14). The parent metal precursor (2), which also has a non-replicating section, is melted and reacted with an oxidant to form a polycrystalline oxidation reaction product which grows primarily only from the positive pattern section of the parent metal precursor (2) and through the filler (14). The molten parent metal is drawn through the growing polycrystalline material and oxidized at the interface between the oxidant and previously formed oxidation reaction product. The reaction is continued for sufficient time to at least partially embed the filler (14) within the oxidation reaction product and form the ceramic composite body containing a negative pattern which inversely replicates the positive pattern of the parent metal precursor (2).
