Abstract

A process for the production of a refractory composite comprises mixing 100 parts of a carbonaceous material (graphite or coke flour, with or without a carbonaceous binder such as pitch) and 10-100 parts of boron, boron + silicon, boron + silicon + one or more of Zn, HfNbTi or boron + one of the above refractory metals, and heating the mixture at a temperature of at least 1800 DEG C. under a pressure of at least 2500 p.s.i. The materials in the second portion of the mixture may be added as such or as compounds of one another or of carbon. The powders should be finely divided and should preferably pass a 200 mesh Tyler screen.ALSO:A process for the production of a refractory composite comprises mixing 100 parts of a carbonaceous material (graphite or coke flour with or without a carbonaceous binder such as pitch) and 10-100 parts of boron, boron + silicon, boron + silicon + one or more of Zr, Hf, Nb, Ti, or boron + one or more of Zr, Hf, Nb, Ti, and heating the mixture at a temperature of at least 1800 DEG C. under a pressure of at least 2500 p.s.i.
