Scrutinyite

The mineral was first reported in 1988 and its name reflects the scrutiny and efforts required to identify it from a very limited amount of available sample material.

Although natural lead dioxide has been known, as the mineral plattnerite (β-PbO2), since 1845,[6] its alpha form could only be recognized in 1981 and reliably identified in 1988.

Identification and characterization of scrutinyite by the standard X-ray diffraction (XRD) technique was hindered by scarcity of material and strong signal interference with plattnerite.

The unusual amount of effort required for the analysis resulted in its name derived from the word "scrutiny".

[4] The crystal structure was deduced by XRD as orthorhombic, space group Pbcn (No.
