Corundum (structure)

Corundum is the name for a structure prototype in inorganic solids, derived from the namesake polymorph of aluminum oxide (α-Al₂O₃). Other compounds, especially among the inorganic solids, exist in corundum structure, either in ambient or other conditions. Corundum structures are associated with metal-insulator transition, ferroelectricity,{{Cite journal |last1=Ye |first1=Meng |last2=Vanderbilt |first2=David |date=2016-04-04 |title=Ferroelectricity in corundum derivatives |url=https://link.aps.org/doi/10.1103/PhysRevB.93.134303 |journal=Physical Review B |language=en |volume=93 |issue=13 |pages=134303 |doi=10.1103/PhysRevB.93.134303 |arxiv=1602.03852 |bibcode=2016PhRvB..93m4303Y |s2cid=56429009 |issn=2469-9950}} polar magnetism,{{Cite journal |last1=Cai |first1=Guo-Hong |last2=Greenblatt |first2=Martha |last3=Li |first3=Man-Rong |date=2017-07-11 |title=Polar Magnets in Double Corundum Oxides |url=https://pubs.acs.org/doi/10.1021/acs.chemmater.7b01567 |journal=Chemistry of Materials |language=en |volume=29 |issue=13 |pages=5447–5457 |doi=10.1021/acs.chemmater.7b01567 |issn=0897-4756}}{{Cite journal |last1=P N |first1=Ravi Shankar |last2=Mishra |first2=Swarnamayee |last3=Athinarayanan |first3=Sundaresan |date=2020-04-01 |title=Polar magnetic oxides from chemical ordering: A new class of multiferroics |journal=APL Materials |language=en |volume=8 |issue=4 |pages=040906 |doi=10.1063/5.0003305 |bibcode=2020APLM....8d0906P |s2cid=216480507 |issn=2166-532X|doi-access=free }} and magnetoelectric effects.

Structure

The corundum structure has the space group hexagonal crystal family#Crystal classes. It typically exists in binary compounds of the type A₂B₃, where A is metallic and B is nonmetallic, including sesquioxides (A₂O₃),{{Cite journal |last1=Manjón |first1=Francisco |last2=Sans |first2=Juan |last3=Ibáñez |first3=Jordi |last4=Pereira |first4=André |date=2019-11-28 |title=Pressure-Induced Phase Transitions in Sesquioxides |journal=Crystals |language=en |volume=9 |issue=12 |pages=630 |doi=10.3390/cryst9120630 |issn=2073-4352|doi-access=free |bibcode=2019Cryst...9..630M |hdl=10261/197158 |hdl-access=free }} sesquisulfides (A₂S₃),{{Cite journal |last1=Sleight |first1=Arthur W. |last2=Prewitt |first2=Charles T. |date=1968 |title=Crystal chemistry of the rare earth sesquisulfides |url=https://pubs.acs.org/doi/abs/10.1021/ic50069a022 |journal=Inorganic Chemistry |language=en |volume=7 |issue=11 |pages=2282–2288 |doi=10.1021/ic50069a022 |issn=0020-1669}} etc. When A is nonmetallic and B is metallic, the structure becomes the antiphase of corundum, called the anticorundum structure type,{{Cite journal |last=Vegas |first=Angel |date=2000 |title=Cations in Inorganic Solids |url=http://www.tandfonline.com/doi/abs/10.1080/08893110008044245 |journal=Crystallography Reviews |language=en |volume=7 |issue=3 |pages=189–283 |doi=10.1080/08893110008044245 |bibcode=2000CryRv...7..189V |s2cid=196777970 |issn=0889-311X}} with examples including β-Ca₃N₂ and borates. Ternary and multinary compounds can also exists in the corundum structure. The corundum-like structure with the composition A₂BB'O₆ is called double corundum. A list of examples are tabulated below.
