Frequently Asked Questions
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.
PHASE Version 5.0 adds hundreds of new diagrams with new expert commentaries to the comprehensive database beyond that available in Version 4.5. The focus of this update is sustainability and clean energy generation.
These systems include numerous complex salt systems containing Li and rare earth elements, ZnO-containing complex oxides and phosphates, mixed Li-based salt-oxides, transition-metal oxides containing rare earths, heavy-metal- (Tl, Te, Pb) or Li-containing semiconductors, transition-metal salt systems, and heavy-metal-containing salt systems.
These newly added diagrams reflect the need for data and emphasis of research efforts on challenges in emerging energy technologies, including corrosion issues in molten-salt Generation IV nuclear reactors, heat-transfer and/or -storage in nuclear as well as concentrated solar power, and development of next-generation batteries.
Other new figures in Version 5.0 provide data pertinent to the recovery/recycling of rare earths; semiconducting systems for laser diodes, photoluminescence, solar cells, displays, chemical sensors, switches, thermoelectrics, and data-storage; non-linear optical materials; spintronics (topological insulators); photoelectrodes (mixed ionic-electrical conductors); photocatalysts; scintillators; thermal-barrier coatings; carbon-storage in the earth's mantle; metallurgical processing methods with reduced carbon emissions; electroceramics for dielectric applications; glass-ceramics for dental restoration materials; and advanced cement for oil wells.
PHASE Version 5.0 brings substantial changes to the PED Viewer used to analyze the diagrams. With the new browser-based programming PHASE 5.0 is substantially easier to install, operate and maintain than previous versions. This is on top of the user-friendly features already built into PHASE, For example, all Figures (the diagrams and commentary for a discrete ceramic materials system) are in .pdf file formats retrieved with a single click and formatted to be printable with book-quality resolution.
PHASE 5.0 no longer requires JAVA. Thus online users can use any operating system such as Chrome, though a mouse (or other pointing device) and keyboard are still required.
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.
PHASE USB and PHASE ONLINE
- Web browser, Chrome or Firefox recommended
- Document viewer for PDF files (Acrobat® or Foxit® or PDF enabled web browser)
- Beginning with PHASE 5.0 (NIST SRD31) Java™ is no longer required. The analysis software uses a state-of-the-art browser-based graphics engine.
- 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
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)

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.
