Thorium232 in natural zirconia 26 Most zirconia (ZrO 2) is manufactured from zircon due to the scarcity of natural zirconia. The radioactivity content of manufactured zirconia depends on the activity of the source zircon and the production process used. Thermal zirconia contains higher levels of radionuclides than the parent

Zircon flour is a fine powder obtained by zircon sand grinding. In Italy, the ceramic industry generally uses zircon flour as an opacifier, thanks to the whitening properties of zirconium (Bruzzi et al., 2000, Righi et al., 2000a). For effective opacifying, zircon sand must be ground to a particle size close to 5 μm.
