Macedonite is a mineral named by Radusinović and Markov in 1971. It has the elemental formula PbTiO3 and exhibits tetragonal crystal system. The type locality is near Crni Kamen, , Prilep Municipality, North Macedonia. It can be confused with perovskite. It is found in an amazonite-rich area.[2]
Fame[]
Lead titanate, which is the premier piezoelectric material, had not been previously reported in the wild.[2]
