Frequently Asked Questions

What is the ACerS-NIST Phase Equilibria Diagram product

The program provides 30,000 relevant, critically-evaluated phase diagrams with commentaries for inorganic compounds (ceramics and glasses), including oxides, non-oxides, salts, carbides, nitrides, borides, compound semiconductors, pnictides and chalcogenides. Also included is the PED Viewer which simplifies the analysis of these complex graphs. This program is the result of a collaboration between the National Institute of Standards and Technology (NIST) and The American Ceramic Society (ACerS) that began more than 60 years ago.

The data are pertinent to a wide variety of applications and include systems of interest for renewable energy technologies (e.g. heat-storage/transfer materials, conversion phosphors, photovoltaics, molten electrolytes, advanced anode and electrolyte materials for battery applications, nuclear-reactor technology and radioactive waste recycling) and next-generation electronic, magnetic, photonic, and optoelectronic devices (e.g. proton conductors, luminescent hosts, solid-electrolyte membranes, liquid-crystal displays, electrochemical sensors, magnetic sensors, actuators, capacitors, transducers, thermoelectric elements, memory elements, fluorescent LED materials, laser hosts, optical fibers, magnetic refrigerators, thermoluminescent elements).   The collection includes data for material systems of interest in other diverse applications such as antibacterial agents, bio-compatible ceramics, cutting materials, fluxes for metallurgical processing/electrolytic refining, improved cement, ceramic filters, semiconductor manufacturing, catalysts and photo-catalysts, thermal‐barrier coatings, pigments, and fuel cells.

What is new with Version 4.4?

PHASE Version 4.4 adds 372 new Figures and 772 new diagrams to the comprehensive database beyond that available in Version 4.3.  The focus of this update is systems for advanced energy.

PHASE Version 4.4 also contains significant usability improvements over Version 4.1 or older. In Version 4.4, all Figures (the diagrams and commentary for a discrete ceramic materials system) are available in .pdf file formats.  In the older versions the diagrams and the commentary were separated and were difficult to attain simultaneously and print.  The .pdf Figures in Version 4.4 automatically contain both the diagrams and the commentary for the system and are readily printable in book-quality resolution.

PHASE Version 4.5 is coming in January 2021.  There will be over 700 new diagrams focusing on sustainability and clean energy generation.  Details coming soon.

What are the available formats for the PHASE product?

USB memory stick (PHASE USB) and web-based subscription (PHASE ONLINE).  Both have single-user and multi-user versions that use username/password verification. PHASE ONLINE has a Library version of that uses IP verification for access anywhere within an institutional or corporate network.

How do I choose the right format?

Answer four questions:

  • How many simultaneous workstations? More than one means multi-user or library version.
  • Will I use this on a MAC or other non-Windows PC workstation that can run JAVA? Yes means PHASE ONLINE
  • Do I have a good internet connection? No means PHASE USB (yes means either will work)
  • Will my funding be ongoing or one-time only? One-time means PHASE USB (note that PHASE USB updates are not automatic and have additional one-time costs)

What are the technical requirements?
PHASE USB and PHASE ONLINE
  • Web browser, Chrome or Firefox recommended
  • Document viewer for PDF files (Acrobat® or Foxit® or PDF enabled web browser)
  • The PHASE (NIST SRD31) product requires installation of Java™ SE version 8.  You can download the latest version at https://java.com/en/download/. PHASE/SRD31 will not operate with any other Java version such as OpenJDK or versions 9 or higher.  Please note that beginning with Java 8 update 211, Oracle enacted the Oracle Technology Network (OTN) License Agreement for Java SE. The new license continues to permit certain uses at no cost (e.g. personal gaming). Other uses, including this application, now require the OTN License and a Java SE Subscription. Consult with your computer/software manager about your organization’s JAVA license status.

    If you cannot use JAVA, then you will still have access to PDF versions of the diagrams.

PHASE USB
  • PC running on Windows® 7 or 10 (Phase USB does not run on MAC or other operating systems)
  • 2 GB RAM, 4 GB hard disk available, dual core processor 1.87 GHz or better
Can I try before I buy?

Yes.  Go to the Free Phase Demo page to view demonstration videos and download the full software with limited trial database.

Which ceramic systems are included in the PED product?
  • Oxides and mixed systems with oxides
  • Chalcogenides (sulfides, selenides, tellurides)
  • Pnictides (N, P, As, Sb, Bi)
  • Carbides, Carbonates, Silicides, and Silicates
  • Actinides (U, Pu, Th)
  • Rare earths (Ce, Gd, Eu)
  • Oxy‐cation systems (molybdates, vanadates)
  • Semiconductors (Si, Ge, Sn)
  • Group 3 systems (B, Al, Ga, In, Tl)
  • Salts including mixed systems with salts
  • Others

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.  For an introductory text on the use and interpretation of phase diagrams, please download General Discussions of Phase Diagrams by F.P. Hall, H. Insley, E.M. Levin, H.F. McMurdie and C.R. Robbins.
