Phase Diagram FAQ

The premier supplier of critically-evaluated phase diagrams for ceramic systems.

 

 

What is the ACerS-NIST Phase Equilibria Diagrams Program?

The program supports growth and progress in the ceramics and glass industry by providing relevant, critically-evaluated phase diagrams for oxides, non-oxides, salts, carbides, nitrides, borides, compound semiconductors, pnictides and chalcogenides. For over 60 years, the National Institute of Standards and Technology (NIST) and The American Ceramic Society (ACerS) have collaborated on the publication of evaluated phase diagrams for ceramic systems. The joint ceramic phase diagram program, representing a continuation and expansion of the effort to make ceramic phase diagram information readily and comprehensively available, began in December 1982.

 

How do I access ACerS-NIST Phase Equilibria Diagrams?

ACerS offers three convenient ways to access the critically-evaluated phase diagrams for ceramic systems:

Why are phase equilibria diagrams important?

Understanding phase equilibria in ceramic systems is central to the use and development of materials in refractories, glass, and other high-temperature technologies. Phase equilibria diagrams answer questions about flexibility and constraints of a ceramic or glass component in high-temperature or high-pressure environments. Phase boundaries also assist in the evaluation of the service stability of a ceramic material, both in the long and short time frames.
