The inherent toxicity of zirconium compounds is low. Hafnium is invariably found in zirconium ores, and the separation is difficult. Commercial-grade zirconium contains from 1 to 3% hafnium. Zirconium has a low absorption cross section for neutrons, and is therefore used for nuclear energy applications, such as for cladding fuel elements.

In dentistry, zirconium is not used as a pure mineral but as a ceramic oxide (zirco-nium dioxide) instead. From a structural point of view, zirconium dioxide comes in three states: cubic, monocline, and tetrag-onal.5 All of these states are unstable at room temperature and must be combined with an element to hold the desired form.
