“…Many borides, carbides, silicides, and nitrides of the early transition metals have been obtained this way in well‐crystallized form, usually with higher purity than by direct reaction of the elemental components. Some of the early literature about metallic fluxes is cited in the introductory paragraphs of various papers reporting on the recrystallization of transition‐metal borides (e.g., TiB 2 , ZrB 2 , VB, NbB 2 , W 2 B 5 ) using iron, copper, aluminum, tin, or lead as fluxes,28–30 the preparation of the high‐melting carbides (e.g., TiC, WC, UC) with iron, cobalt, nickel, or aluminum as fluxes,31 and the preparation of various silicides of early transition metals (e.g., TiSi 2 , CrSi 2 , Mo 5 Si 3 , MoSi 2 , W 5 Si 3 , WSi 2 ) employing mainly copper or tin as fluxes 32. 33 Deitch reviewed the early literature on the growth of semiconductors, e.g., Si, SiC, AlP, GaAs, ZnS, ZnTe, ZnSiP 2 , CdSiP 2 ,34 and Lundström summarized the literature on the preparation and crystal growth of non‐oxidic refractories using molten metallic solutions 35.…”
