– Stoichometry ZrO2
– Mohs hardness 8.0-8.5
– Cubic (Hermann Mauguin: Fm-3m [225])
Zirconium is not too abundant but
within the its 5th period in the PTOE
and beyond it is most abundant.
It is cubic but a different structure than
diamond and III-V semiconductors with slightly higher symmetry.
It feature a a network of covalent Zr-O bonds
that follow the edged of a spacefill of rhombic dodecahedral cages with …
– Zr atoms at the sharp corners in {100} directions
– O atoms at the blunt corners in {111} directions
