Abstract
A method is provided for forming machinable ceramic compacts, which are in the unfired, preconsolidated condition. The method of this invention adds the binder to the ceramic powder mixture after the compact is formed by compaction, as opposed to conventional practice wherein the binder is added to the mixture prior to compaction. The unfired ceramic compacts which are formed by the method of this invention are characterized by high strength, excellent durability and enhanced machinability.
