Setting expansion correlates with the heat of reaction. The heat of reaction and setting expansion vary considerably according to the thickness of the rings. The heat of reaction and setting expansion decrease as the thickness of the rings increases. In this work, we examined the relation between the heat of reaction and setting expansion of investment materials. Results were as follows: 1) With a ring of stainless steel which absorbs the heat of reaction from the investmest material, setting expansion is small. 2) The heat of reaction increases as the quantity of CERAVEST increases. However, setting expansion does not increase. 3) The heat of reaction and setting expansion increases as the quantity of CERAMIGOLD increases. 4) Setting expansion influences the time required for the setting. In a long period of time, setting expansion is small. 5) The above results indicate that there is a correlation between the heat of reaction and setting expansion.}, pages = {366--373}, title = {リン酸塩系埋没材について(その5)硬化時の反応熱と膨張について}, volume = {12}, year = {1986} }
