Notes:
Authors state that system exhibits simple eutectic behavior.
Method/Apparatus/Procedure:
Samples were equilibrated in an apparatus similar to the one used by Ott and co-workers (see J. Phys. Chem. 1962, 66, 1387). Temperature of the sample monitored with an Omega RTD probe inside a stainless steel tube that went down through the center of the pyrex tube. Samples heated above their melting point temperature, and time-temperature cooling curves were measured.
Source and Purity of Materials:
(1) 99.5 %, Aldrich Chemical Company, Milwaukee, Wisconsin, USA, was recrystallized before use.
(2) 99.5 %, Aldrich Chemical Company, was recrystallized before use.
