THE HEAT OF DECOMPOSITION OF TRICALCIUM SILICATE INTO BETA- DICALCIUM SILICATE AND CALCIUM OXIDE

THE RESULTS ARE PRESENTED OF A REDETERMINATION, BY AN IMPROVED METHOD, OF THE HEAT OF THE REACTION. THE HEAT OF SOLUTION METHOD WAS USED, BUT BETA DICALCIUM SILICATE AND CALCIUM OXIDE WERE DISSOLVED TOGETHER AS EQUIMOLAR MIXTURES RATHER THAN SEPARATELY AS IN EARLIER INVESTIGATIONS. THE RESULT WAS THE EXCHANGE OF 296H = -2100 CAL./MOLE. THE ESTIMATED UNCERTAINTY WAS PLUS OR MINUS 200 CAL./MOLE. /PCA/
