NASA Tech Briefs announce new technology derived from the U.S. space program. They are issued to encourage 
commercial application. Tech Briefs are available on a subscription basis from the National Technical Information 
Service, Springfield, Virginia 22151. Requests for individual copies or questions relating to the Tech Brief program may 
be directed to the Technology Utilization Office, NASA, Code KT, Washington, D.C. 20546. 
Phase-Change Materials Handbook 
Phase-change materials are a particular group of sub-
stances with the unique ability to absorb and liberate 
large quantities of heat without an appreciable temper-
ature change. To date, the major effort in phase-change 
materials technology has been largely confined to pre-
liminary theoretical and empirical research; however, to 
determine the practicality of the technique, flight 
systems using phase-change materials have been sched-
uled for testing in a major space effort. The materials 
handbook provides the theory and data needed by the 
thermal design engineer to bridge the gap between 
research achievements and actual systems. 
The handbook describes the relationship between 
phase-change materials and more conventional thermal 
control techniques. Also, the handbook discusses numer-
ous space and terrestrial applications of the materials. 
Material properties of the most promising phase-change 
materials are provided, along with the purposes and use 
of metallic filler materials in phase-change material 
composites. Information on packaging problems, the 
effects of bubble formation, supercooling, and other 
design and performance considerations are included. In
addition, methods of obtaining data not currently 
available are presented. A discussion of computational 
tools useful to the designer is also included in the hand-
book.
