This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors.

The most common oxide is zirconium dioxide, ZrO 2, also known as zirconia. This clear to white-coloured solid has exceptional fracture toughness (for a ceramic) and chemical resistance, especially in its cubic form. [37] These properties make zirconia useful as a thermal barrier coating, [38] although it is also a common diamond substitute. [37]
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).
Zircon (/ ˈ z ɜːr k ɒ n,-k ən /) [7] [8] [9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium.Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO 4.
The FBI identified Shamsud Din Jabbar of Texas as the suspected truck driver who crashed into a New Year's Eve crowd at high speed in New Orleans.
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 ]
