2. Diamond simulant - Wikipedia

   en.wikipedia.org/wiki/Diamond_simulant

   Cubic zirconia can be coated with diamond-like carbon to improve its durability, but will still be detected as CZ by a thermal probe. CZ had virtually no competition until the 1998 introduction of moissanite (SiC; silicon carbide). Moissanite is superior to cubic zirconia in two ways: its hardness (8.5–9.25) and low SG (3.2).

   Cubic zirconia is relatively hard, 8–8.5 on the Mohs scale—slightly harder than most semi-precious natural gems. [1] Its refractive index is high at 2.15–2.18 (compared to 2.42 for diamonds) and its luster is Adamantine lustre .

7. Ceria-zirconia - Wikipedia

   en.wikipedia.org/wiki/Ceria-zirconia

   Ceria-zirconia is widely used as a component in current three-way catalytic converters. [6] The ceria-based component of the converter has several functions, including promoting the dispersion of the noble metals in the catalyst, but also storing and releasing oxygen. [ 7 ]
