ABSTRACT:
This invention is concerned with methods and materials for producing unitary silicon nitride structures by means of joining together at least two silicon based bodies with an intervening mixture of silicon powder and a heat removable liquid binder therefor between the joining faces, mantaining said faces in juxtaposition and slowly heating the assembly in a nitriding atmosphere to remove the liquid binder and to convert the material of said bodies and the intervening silicon powder into a unitary structure.
