Yttriaite-(Y) is an exceedingly rare mineral, a natural form of yttrium oxide, Y2O3.[2][1] In terms of chemistry it is yttrium-analogue of kangite, arsenolite, avicennite and senarmontite (isometric minerals).[3][4][5][6] Other minerals with the general formula A2O3 include corundum, bismite, bixbyite, eskolaite, hematite, karelianite, sphaerobismoite, tistarite, and valentinite.[7] Yttriaite-(Y) forms tiny inclusions in native tungsten.[2]
