T. Leskela et al., SYNTHESIS AND THERMOANALYTICAL CHARACTERIZATION OF 2 POLYMORPHS OF SAMARIUM SULFITE TRIHYDRATE, Thermochimica acta, 262, 1995, pp. 195-207
A new polymorph of Sm-2(SO3)(3) . 3H(2)O (beta-form) has been synthesi
zed and its properties are compared to those of the previously known a
lpha-form. The polymorphs have been characterized by X-ray diffractome
try, FTIR spectroscopy and thermal analysis. The thermoanalytical stud
ies, particularly by simultaneous TG and DTA, as well as by EGA with b
oth MS and FTIR detection, show distinct differences between the two p
hases.
