High Temperature Oxide Melt Solution Calorimetry
June 27-28, 2017
Peter A. Rock Thermochemistry Laboratory, UC Davis
AlexSYS is the commercial version of custom-built Tian-Calvet twin calorimeters, which are the heart of the Peter A Rock Thermochemistry Laboratory. The instruments have been used for over forty years, with constant improvements, to study the thermodynamic properties of bulk and nanosized metals, alloys, complex mixed oxides, carbides, nitrides, sulfides, etc. (e.g. enthalpy of formation, enthalpy of transition, vitrification, fusion, enthalpy of reaction, surface energy). Although Setaram has built calorimeters for high temperature operation for many years, the first commercial high temperature Tian-Calvet AlexSYS twin calorimeter was built by Setaram in 2010. It is currently in use at TU Freiberg Germany. A total of nine AlexSYS calorimeters exist worldwide, and the number of users increases every year.
This workshop will focus on basic and advanced topics in high temperature oxide melt solution calorimetry measurements performed on the AlexSYS. The first day will open with a brief presentation of the calorimetry technique, the instrument, and selected important applications. The participants will share their experiences with high temperature calorimetry, current projects and interests, and future plans.
The second day will be dedicated to technical topics of common interest to stimulate future collaborative work, discuss new challenges in experimental oxide melt solution calorimetry, and demonstrate new refinements in methodology. There will also be a discussion of possible joint proposals, including a thermodynamics-focused DOE EFRC. The workshop will be followed by an optional two days of advanced training on AlexSYS systems.
The participants, all former and current users, are from the University of California, Davis; University of Notre Dame, Clemson University, Washington State University, Los Alamos National Laboratory, and the Pacific Northwest National Laboratory. The workshop will be of special interest to any researchers contemplating adoption of these calorimetry techniques in their work.
