Abstract :
Solid solutions TiNiSn1-xMe´x (Me´=Al,Sb,Bi) and ZrNi1-xMe´´xSn (Me´´=Cr,Mn,Cu) with MgAgAs structure type were obtained on the basis of the TiNiSn and ZrNiSn semiconducting compounds. X-ray analysis was used to define the stability range of the solid solutions. The temperature dependence of the resistivity and thermopower showed a loss of semiconducting properties. The sign of thermopower remains negative for all solid solutions
