We employed two types of cement bonded investments in this study. One of the casting molds was "Titavest MZ" for metal frame work, and the other was "Titavest CB" for crown and bridge work. The molds temperature were prepared at room temperature, 300℃, 600℃, and 900℃ for each, respectively. When the mold temperature was set at a high range with "Titavest MZ", high percentage of castability was gained. Mold temperature at "Titavest MZ" showed a statistically significant correlation on the castability (p<0.1). On the other hand, "Titavest CB" showed high percentage of castability under every condition. Above results were not quitely explained only by this present study. But, it was realized that at least two different types of investing materials were present; one which had a positive relation to the mold temperature, and the other which had a negative one in relation to the pure titanium castsbility., application/pdf}, pages = {166--170}, title = {純チタンの鋳造性に関する研究(第2報) : 埋没材と鋳型温度の違いが鋳込率に及ぼす影響について}, volume = {21}, year = {1995} }
