Abstract

Single crystals of BaTiO$_{3}$ which were grown by Remeika's method were on reducing them is hydrogen atmosphere at about 400-1000.deg. C for about 30hrs. They became light brown and seems to have an effect on their properties by oxygen deffects especially at a Curie temperature of 122.deg. C exhibitted abnormal reducting resistivity. These semiconducting tendency were studied experimentally by observing through several electrical properties and were discussed on the basis of exchange semiconductor mechanism.
