The phase of Pb2CrO5 composition is a ceramic material with dielectric properties and probably with interesting optical characteristics. It can also be formulated as PbCrO4 · PbO, which reveals a structural analogy with lanarkite, PbSO4-PbO, and PbMoO4 · PbO. In order to achieve an advance in the spectroscopic characterization of materials of this type, we have investigated the infrared and Raman spectra of this phase.
