PHASE Demonstration

The PHASE database and PED viewer software are extremely easy to use. If you want to see how it’s used or take your own test drive, click below to go to our PHASE Demonstration page.

The demonstration download has the fully operational software with the complete index of the figures in Version 5.2. However, the demonstration has only small subset of the figures available to download and analyze.

Background Information

The American Ceramic Society published its first issue of “Phase Diagrams for Ceramists” in the October 1933 issue of the Journal of the American Ceramic Society. It featured 178 diagrams with supporting explanatory material. Ceramic researchers then recognized the diagrams’ great value in saving time and money in research. Fast forward nine decades, and researchers still count on ACerS-NIST Phase Equilibria Diagrams to provide the most trusted, comprehensive collection of critically evaluated phase diagrams for ceramic and inorganic systems for understanding temperature-dependent materials interactions.

"...The best available source of phase diagrams of ceramic systems"

"I highly recommend the database because it is comprehensive and fully vetted by NIST. We trust the diagrams in the database."

William Fahrenholtz, professor of ceramic engineering, Missouri University of Science and Technology

“I played around with the ceramic phase diagram software (it's extremely awesome). I found all 3 phase diagram types for systems of alumina, ceria and zirconia. Alumina seems to be fine with ceria as long as we are below 1750ºC, but funky things happen with ceria and zirconia at high temperatures. Doing actual analysis and powder synthesis made me appreciate the software a lot more. I will use alumina trays or boats of some sort instead of zirconia.”

“... extremely useful for identifying new areas of research.“

Theodore M. Besmann

Ph.D.

“I want to express my very strong support for the ACerS-NIST Phase Diagram program. Over the decades of my leading a research group at the Oak Ridge National Laboratory, and now as a university faculty member I have regularly looked to the compendia of phase diagrams for fundamental information for my and my group’s research. The documentation together with the carefully assessed diagrams is a tremendously extensive database that can be consistently relied upon. I have referred countless colleagues to the Phase Equilibrium Diagrams as an important resource for their research and development efforts.”

Juan Claudio Nino

“When focusing on materials design and discovery, whether in computationally- or experimentally-led endeavors, starting with phase equilibria is of primal importance. Having a curated and centralized database of phase diagrams such as the PED maintained by ACerS-NIST is an essential resource supporting the advancement of ceramics.”

Paul J. McGinn

We rely on access to Phase Equilibria Diagrams for both our research and in teaching. In my research, we utilize them on a weekly basis. Students are often synthesizing compounds for solid state battery work and need to select appropriate process temperatures based on guidance from phase diagrams. In my research on glasses as catalysts for diesel particulate filters access to phase diagrams has been invaluable for selecting compositions and in devising new glass formulations. I also use Phase Equilibria Diagrams in my teaching. I regularly illustrate concepts in materials processing by utilizing phase diagrams. I also use them in teaching students how to decipher ternary phase diagrams. I strongly support continuation of the ACerS-NIST phase diagram project.

“Phase diagrams are critical to understanding stability, developing processing procedures and identifying new materials. Having a compilation of the available phase equilibrium data that are reviewed and searchable is an invaluable resource for materials scientists and engineers.”

“...saves me a lot of time...“

“Trying to work without consulting a phase diagram first is like trying to travel without a map—and ACerS is the best source of maps around— it’s the Rand McNally Atlas of ceramics.”

Industry Researcher

The ACerS phase diagram database is a useful tool as it provides quick access for searching through various ceramic systems. It is much more efficient than trying to comb through individual papers. In addition to pulling up the actual phase diagrams, the database also provides a valuable insight into what work has been done in various systems.

Industry Researcher

We are in the business of developing new materials that are based on ceramics/glasses and therefore regularly have to refer to the phase diagrams. We use both old paper versions we have on the bookshelves but for internal reports and presentations having the electronic versions present makes it much easier to pinpoint the areas of phase diagrams we are working in. The binary and ternary diagrams are the most useful for us.

The Offer

Not long ago, the ACerS-NIST Phase Equilibria Diagrams and commentaries were published in hard copy books. We went through our warehouse and found we have a few copies remaining for many of our older volumes. These out-of-print works are available in very limited quantities. So if your library needs one of these volumes to complete your collection or replace a lost volume, you should act fast.

The price for our books have been reduced so that we can get them out of our warehouse and onto your shelves. Nonmember price for each book is $100; member price is $50 per book.

Phase Equilibria Diagram Expert Information

Reliable Content, Useful Tools

Researchers have created tens of thousands of phase equilibria diagrams since James Thomson (brother of Lord Kelvin) constructed a plaster pressure-volume-temperature 3-d model based on data for carbon dioxide collected by Thomas Andrews. James Maxwell made his better known thermodynamic surface sculpture in 1874, based on the graphical thermodynamics papers of Josiah Gibbs.

With so many diagrams in the scientific record, how can modern ceramic and glass researchers find the appropriate phase equilibria diagrams for their own work?

  • Look up all the papers throughout history on the specific ceramic or glass system and read thoroughly. OR
  • Consult the ACerS-NIST Phase Equilibria Diagram database where each Figure contains commentary on the diagram(s) for a specific material system.
