    Abstract: A binary compound XY is formed by mixing two exothermic reacting elements X and Y together and heating to above the melting point of the element X having the higher melting point; X being of particle size, e.g. less than 44 m , such that it is all consumed. One of the elements may be from Group IIb (Zn, Cd, Hg) or IIIB (Ga, In, T1) and the other from VB (P, As, Sb) or VIb (S, Se, Te). Particles of Y may be 1/8 -inch, or the same size as X. A metallic element, e.g. Cd, may be used with an oxide coating, or this may be removed by treating with concentrated aqueous ammonia, washing, and drying in air or vacuum at 100 DEG C., or by reducing in H2 at 200 DEG C. The mixture of X and Y is placed in an ampoule which is evacuated or filled with an inert gas and sealed, then heated at 0.1 to 5 DEG C. per min. to 5-100 DEG C. above the melting point of X and cooled slowly or by air quenching. The product may be ground and the heating cycle repeated.
