Phase Equilibrium Diagram Product Details
Critically evaluated ceramic phase diagrams from 1898 to today
available material system
The ACerS-NIST Phase Equilibria Diagrams product is the largest collection of data on compositions, phase structure and phase transition temperatures for inorganic materials. Other phase equilibria collections may have some inorganic compounds, but their focus is on other material types such as metals and alloys, or organic systems. Gathered from critically-evaluated literature sources going back to 1898, the Phase Equilibria Diagrams cover a wide range of compositions, including but not limited to:
- Oxide systems and mixed systems with oxides for electrodes, catalysts, electroceramics, magneto-resistors, thermistors, capacitors, nuclear fuel/waste, ion conductors and more
- Chalcogenides such as sulfides and selenides for thermoelectrics, optoelectronics, photovoltaics, etc.
- Pnictide systems such as nitrides and arsenides for optical materials, sensors, detectors, photovoltaics, etc.
- Actinide and Rare Earth systems containing U, Th, Pu, Ce, Eu, Gd for nuclear materials research and luminescence, etc.
- Oxy-cation systems such as molybdates and vanadates
- Semiconductors – Si, Ge, Sn
- Group 3 systems – B, Al, Ga, In, Tl
- Group 4 systems – carbides, silicides for high temperature systems
- Glass systems – silicates, borosilicates
- Salts and minerals
Want to see if your system is included in the database? Download the demonstration version and search the cumulative index.
- Search by elements and components with many boolean operations built in for narrowing or expanding your results. Or view the cumulative index.
- Not sure of the ideal element combination? Search by application or other text in the commentaries.
- The preview window gives insight into the format of the phase equilibrium diagrams within the PED figure so you can choose the best one for your needs.
- View the complete Figure (PDF) or view/analyze the diagram using the PED viewer
- Each PED Figure consists of the diagrams and commentary for a single chemical system. The commentary lists the information used to generate the diagram(s). Many Figures also contain comments about applications, new information on the chemical system, etc. Each Figure is formatted for easy reading and printing in book-quality resolution. Download an example Figure.
- The PED Diagrams are formatted to be viewed and analyzed in the PED Viewer. The PED Viewer is based on PED Editor, the JAVA-based program developed at NIST by Eric Boesch. The Viewer allows users to extract temperature and composition information, follow solidus and liquidus lines, view diagrams on both mole and mass bases, and even swap axes to enable viewing according to the needs of the researcher. Give the Viewer a test drive (go to Phase Demo page).
PHASE USB – a physical USB stick containing the Version 4.3 database and software. It is loaded onto your local personal computer that runs the Windows® 7 or 10 operating system; no internet required. The PHASE USB product is a one-time purchase that can be used for many years. However, when new diagrams are added, updates to the PHASE USB product carry must be purchased, usually at a significantly discount price depending on which version is being upgraded.
PHASE ONLINE – a cost-effective and convenient subscription web-based service that must be renewed annually. The database is always current for this service. Not tied to any one workstation, PHASE ONLINE can be accessed from any computer connected to the internet. This is the only format available to MAC users.
PHASE BOOKS – Need to complete your book library or replace a damaged copy? ACerS has a very limited number of the some of the original volumes of phase diagrams used to create Phase Equilibria Diagram products. Click here to see what is currently available.
Single-user versions of both PHASE USB and PHASE ONLINE allow one person at a time to search the database and view the diagrams.
Multi-user PHASE USBs allow loading of the software onto up to 10 PCs
Multi-user PHASE ONLINE subscriptions allow 10 username/password combinations
Library PHASE ONLINE subscriptions allow unlimited simultaneous users via IP Authentication
