The electrical conductivity σ and the thermal conductivity λ were investigated at varying
temperature (40< T< 120° C) for two sulphate compounds, anhydrous mercury (II) sulphate
HgSO_ {4} and cerous (III) sulphate Ce_ {2}(SO_ {4}) _ {3}· H_ {2} O. It seems likely that
each of the two sulphate salts undergoes structural phase transition around 90° C. The
differential thermal analysis thermogram was carried out as an aid for confirming of the
observed phase transitions. The mechanism of the heat transfer is mainly due to phonons. ...
