Abstract

The neutron diffraction patterns of molten KxTe1-x alloys for x=0.12 and x-0.50 demonstrate the persistence of covalently bonded tellurium in the liquid. In the case of liquid K0.12Te0.88, the measured structure is domianted by the Te-Te contribution, and is remarkably similar to that of pure liquid tellurium. The equiatomic alloy K0.50Te0.50 is shown to contain mostly Te pairs which are identified with Zintl ions, Te22-. The presence of these ions explains the semiconducting behavior of these alloys deduced from recent electrical transport measurements.
