// Workers AI · dad joke modeWhat did the Quaternary phase say? It's in a 4th state of mind.

From Wikipedia, the free encyclopedia
YBa2Cu3O7, abbreviated YBCO is a famous quaternary phase. It features four elements: yttrium (Y), barium (Ba), copper (Cu), and oxygen (O).

In materials chemistry, a quaternary phase is a chemical compound containing four elements. Some compounds can be molecular or ionic, examples being chlorodifluoromethane (CHClF2) and sodium bicarbonate (NaCO3H). More typically quaternary phase refers to extended solids. A famous example are the yttrium barium copper oxide superconductors.[1]
