R. Sole et al., HIGH-TEMPERATURE SOLUTIONS OF THE (0.4NA(2)O-0.6B(2)O(3))-BAO-((6-X)FE2O3- PHYSICAL-PROPERTIES(XCOSNO(3)) SYSTEM ), Materials research bulletin, 30(6), 1995, pp. 779-788
In this paper the thermal dependences of the viscosity, density and su
rface tension of several solutions of the (0.4Na(2)O-0.6B(2)O(3)) - Ba
O - ((6-x)Fe2O3 + xCoSnO(3)) system containig four different degrees o
f substitution of Fe3+ by Co2+ + Sn4+ have been determined experimenta
lly. On the basis of all these sets of results, the solution compositi
ons with the highest solvent contents have been proposed for the growt
h of BaFe12-(x+y)CoxSnyO19 using a TSSG/slow cooling methodology.
