Abstract

A hollow graphite core for use in moulding hollow articles or tubes from powdered beryllia, magnesia, thoria, zirconia, uranium and plutonium oxides, and cermets is made of such a strength that after hot pressing of the material in graphite dies, the contractional force on cooling will crush the core, yet the core is strong enough to withstand the pressing.
