Phase Equilibria Diagram Database 3.1

Phase Equilibria Diagram Database is a curated, searchable resource of critically evaluated phase diagrams for ceramic and other inorganic systems, developed by The American Ceramic Society (ACerS) in partnership with the National Institute of Standards and Technology (NIST). Built on decades of literature assessment and editorial review, it consolidates authoritative diagrams, expert commentary, and complete bibliographic references to help users understand phase relationships, stability fields, and processing windows.

Key features

• Comprehensive coverage: Binary, ternary, and higher-order systems across oxides and non-oxides, including glasses, refractories, electronic and energy materials, and other ceramic-relevant systems.
• Critically evaluated content: Each diagram is selected from the published literature and reviewed by ACerS/NIST editors, with annotations and source citations for rapid verification.
• Powerful search: Find diagrams by chemical system, components, formula, keywords, author, journal, and more, with tools to navigate related systems and cross-references.
• Rich diagram types: Isothermal and isoplethal sections, liquidus surfaces, compatibility diagrams, metastable fields where available, and associated notes that aid interpretation.
• Practical workflow support: Zoomable viewing, citation export, and image download options designed for research, teaching, reports, and production documentation.
• Regular updates: New and revised diagrams and comments are added periodically to reflect the latest vetted research.

Who it’s for

• Materials scientists, ceramic engineers, and glass technologists
• Researchers and practitioners in refractories, electronics, energy, and advanced ceramics
• Geoscientists and cement/concrete specialists studying mineralogical systems

Typical uses

• Selecting compositions and processing temperatures
• Predicting phase stability, compatibility, and reaction paths
• Interpreting XRD results and designing heat-treatment schedules
• Reducing trial-and-error in materials development and manufacturing

Access is provided via a subscription-based web platform maintained by ACerS and NIST.
