En. Soloveva et al., KINETICS AND MECHANISM OF REACTION BETWEEN LN(2)O(3) (LN=ND,EU,YB), CUO, AND BACO3 DURING SYNTHESIS OF LNBA(2)CU(3)O(X) AND YB2BACUO5, Inorganic materials, 32(8), 1996, pp. 872-876
DTA, TGA, XRD, and coulometric titration were used to study the kineti
cs of reactions between BaCO3, Ln(2)O(3) (Ln = Nd, Eu, Yb), and CuO an
d the sequence of chemical transformations during synthesis of LnBa(2)
Cu(3)O(x) and Yb2BaCuO5 at temperatures 850-950 degrees C. The conditi
ons necessary for synthesis of single-phase products were identified.
