Abstract

As an article for manufacture, a tin, lead, indium, and alloys of each, admixed with a carbide or carbonyl former, for forming these with said tin, lead and indium, and their alloys into an "active" alloy form; these "active" alloy forms are suitable for making wettable carbon, graphite, diamond, sapphire, alumina, metal carbide, quartz, silicon metal, etc., composites which will not dewet upon heating but form strong bonds; methods for preparing said composites of various shapes, layers, coatings, and sandwiches; alloys, preforms and various metal-graphite, diamond, sapphire, alumina, metal carbide, quartz, silicon metal etc., structures also disclosed.
