The Li2SO4 system containing various mol% of CaSO4 were synthesized. The structure and the electrical conduction of these system were studied at the temperature from 20 to 700℃. In the region of CaSO4 mol ratio higher than 0.05, it could be confirmed that Li2SO4-CaSO4 system does not form solid solution. Due to the substituted Ca2+, the transition temperature (monoclinic to cubic) is shifted to the low temperature. The ionic conduction of monoclinic Li2SO4-CaSO4 increased with increasing lithium vacancy which was produced by substituted Ca2+, but that fcc Li2SO4-CaSO4 was not influenced by the substituted Ca2+ ion.
