Abstract
The quick heating technique has a great advantage in casting procedures, therefore, several products made of not only gypsum-bonded investments but also phosphate-bonded investments are available on the Japanese market.In this study, properties, such as fluidity, setting expansion, thermal expansion, surface roughness and powder particle size distribution of phosphate-bonded investments for quick heating casting were compared with those of conventional phosphate-bonded investments.There were only a few differences between properties obtained from quick heating investments and those obtained from conventional investments, with the exception of carbon presence for conventional investments and slight differences in powder particle size distribution among these investments.
