“…Because of the convenient eutectic temperature, the naphthalene-camphor alloy has been studied by metallurgists as a model for solidification. [17][18][19] This eutectic alloy seems suitable for a vehicle for room-temperature freeze casting in terms of not only a convenient solidification temperature of 31-32°C but also a low liquid viscosity, negative volume change during solidification, and higher vapor pressure, all of which are expected from the properties of pure naphthalene and pure camphor.…”

Freeze casting for Al 2 O 3 was accomplished at room temperature with nonaqueous sublimable vehicles in the naphthalenecamphor eutectic system with a eutectic temperature of 31°C. A fully dense sintered body (>99.5% of theoretical density (T.D.)) was obtained with a eutectic composition vehicle, whereas at most 90% T.D. was obtained with an off-eutectic (i.e., hypo-or hypereutectic) composition vehicle due to formation of large uniquely shaped voids. Microstructural observation suggested that growing pro-eutectic crystals rejected the suspended Al 2 O 3 particles to form large voids during the solidification process. At the eutectic composition, formation of fine lamellar microstructure in a solidified vehicle is considered to inhibit particle rejection resulting in large voids.
