Abstract
Disclosed is a method capable of forming complex green body shapes containing alumina for forming into ceramic products. The method comprises providing a slurry containing alumina powder and an aqueous solution in an amount to provide a high level of solids in the slurry and adding to the slurry rehydratable alumina powder to provide a mix, the rehydratable alumina being present in an amount sufficient to cause the mix to harden. The mix is then permitted to harden to a solid body suitable for firing into a ceramic product.
