Abstract:

The binary and ternary systems M'O(M'CO3)-Nb2O5 and M'O(M'CO3)-MO-Nb2O5, where M'=Ca, Sr and Ba and M=Cu, Ni, Cd, Zn and Pb, were investigated by means of thermal analysis in the temperature range 20-1500 degrees C. The boundaries of stability of the solid solutions Sr-2-xMe(x)Nb(2)O(7), Sr-2-xM(x)Nb(2)O(7), Sr-4-xM(x)Nb(2)O(9) and Sr-6-xM(x)Nb(2)O(11) were determined by means of X-ray diffraction, and IR and Raman spectroscopy. The possibility of prognostication of the phase fields of stable solid solutions by calculation from the diagrams of the `comparative electronegativity of atoms vs. tolerance factor' was demonstrated. The kinetic parameters of the interactions in the SrCO3+MO+Nb2O5 powder mixtures were established.
