This question will resolve Yes if any lead apatite family material is found to be a superconductor at temperatures above 30K and ambient pressure before 2025.

The lead apatite family will be defined to include any material that:

• Consists of at least 75% by mass of some combination of lead, oxygen, and phosphorous;

• Contains at least 1 phosphorous atom per 3 lead atoms. (For comparison, LK-99 is 97.5% lead, oxygen, and phosphorous, with 2 phosphorous atoms per lead atom.);

• Has an atomic atomic ratio of at least 1:1 Pb:Cu, and;

• Is at least 10% lead by mass.

Resolution will be based on published, peer-reviewed results with published replications.

This question is intended to mirror the metaculus question:

The above definition of the lead apatite family is bad; suggestions very much welcome!
