ABSTRACT:
In accordance with this invention, there is provided a process for producing a shaped article in which a reaction mixture containing at least two elemental materials is first charged into a die to form a shaped green body. A uniaxial pressure of from about 500 to about 5,000 pounds per square inch of cross-sectional area of the green body is then uniaxially applied to the green body, and the green body is then ignited; during ignition, the uniaxial pressure of from about 500 to about 5,000 pounds per square inch is maintained at a substantially constant level and continually applied to the reaction mixture.
