Zirconium dioxide of Mars to provide both fuel and oxidizer that could be used as a store of chemical energy for use with surface transportation on Mars. Carbon monoxide/oxygen engines have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced by zirconia electrolysis without requiring use of any of the Martian water resources to obtain hydrogen, which would be needed for the production of methane or any hydrogen-based fuels. Zirconia is also a potential high-k dielectric material with potential applications as an insulator in transistors. Zirconia is also employed in the deposition of optical
Cubic zirconia diamond: Cubic zirconia, as a diamond substituent and jewel competitor, has been seen as a potential solution against conflict diamonds and the controversy surrounding the rarity and value of diamonds. Regarding the latter, the main argument presented being that the paradigm where diamonds were seen as rare due to their visual beauty is no longer the case and instead has been replaced by an artificially rarity reflected in their price. This is attributed to confirmed evidence that there were price-fixing practices taken by the major producers of rough diamonds, in majority attributed to De Beers Company known as to holding
