Kangite is an exceedingly rare scandium mineral, a natural form of impure scandium oxide (Sc
2O
3), with the formula (Sc,Ti,Al,Zr,Mg,Ca,□)
2O
3. It crystallizes in the cubic crystal system diploidal class.[1] In terms of chemistry it scandium-analogue of tistarite. Both kangite and tistarite were discovered in the Allende meteorite.[2][1][3][4]
