API - Filter structures by elements

Materials Project Materials Project Data/API

Dear developers,

I’ve been using the API of materials project to download a large quantity of materials. Ideally I would like to avoid materials that contain certain elements, such as radioactive ones. Is it possible to filter out any materials that contain certain atomic species? I tried to use the “elements” or “chemsys” field but neither of them apply to this case. Thank you very much in advance.

Hi @bcucco,

You should be able to use the exclude_elements field. For example, mpr.materials.summary.search(exclude_elements=["Si", "O"])
