The temperature-dependent impurity distribution of NaCl: Sr++ and the NaCl: Mn++ systems was studied by using the measuring methods of microhardness, flow stress, conductivity and the gold decoration method. The results show that with increasing quenching temperature the measured values of mechanical and electrical characteristics increase monotonously up to a point characterized by the impurity. This is in accordance with our decoration studies; the impurities dissolve gradually into the lattice with increasing temperature. In the NaCl: Sr++ system there are needle-like precipitates whereas the NaCl: Mn++ system produces rectangular parallelepipedons. The size of these formations decreases with increasing quenching temperature.
