Functional ceramic materials database: an online resource for materials research

Prior research has shown that ceramic materials are essential in electronic and energy applications. However, a lack of centralized data on ceramic properties remains a challenge. Existing databases often focus on specific material types or properties. This gap motivated the creation of a more comprehensive resource. Literature data sets have provided foundational information, but they lack integration into a single platform. Combinatorial experiments offer a way to generate new data efficiently. No prior work had resolved the need for a publicly accessible database covering multiple ceramic properties. This paper introduces a database designed to address these limitations and expand research possibilities.

The aim is to develop a publicly accessible database for ceramic materials data. This resource is intended to include both literature-derived and experimentally generated data. The focus is on electroceramic materials and oxygen ion conductors, which are central to many applications. The database is designed to be flexible, allowing for the inclusion of diverse measurement types. Researchers can use this database to access and analyze data relevant to their specific interests. The study emphasizes the potential of the database to evolve as more data become available. The goal is to create a generic resource that supports a wide range of ceramic materials research. This approach aims to streamline data access and encourage broader scientific collaboration.

The database was built using data from literature sources and combinatorial experiments. Combinatorial experiments were conducted on the London University Search Instrument to generate new data. Data collection focused on two main groups of materials, primarily from the perovskite family. The database design allows for the inclusion of various types of measurements and properties. Permittivity measurements of electroceramic materials were one of the primary data categories. Ion diffusion measurements of oxygen ion conductors formed the second major data category. The database structure is modular, enabling future expansion with additional material types. Data entry and storage were designed to ensure accessibility and usability for a broad audience.

The database currently contains data on two main groups of ceramic materials. Perovskite-based materials are the primary focus, with data on permittivity and ion diffusion. Permittivity measurements provide insights into the dielectric properties of electroceramic materials. Ion diffusion measurements help assess the performance of oxygen ion conductors. The database includes data from both literature sources and new combinatorial experiments. The modular design allows for the inclusion of additional material types and measurement types. As data accumulate, the database is expected to grow into a generic ceramic materials resource. The database is publicly available and designed for use by a wide range of researchers.

The database provides a valuable resource for ceramic materials research. It includes data on permittivity and ion diffusion, two key properties of interest. The database design supports the inclusion of diverse measurement types and material categories. The authors propose that the database will evolve as more data become available. The use of combinatorial experiments enhances the database's utility and scope. The database is intended to be a public resource accessible to a broad audience. The authors suggest that the database may become a standard tool for ceramic materials research. Future work may expand the database to include additional material types and properties.
