Vanadium oxide

Vanadium oxide mainly refers to:

Vanadium(II) oxide (vanadium monoxide), VO
Vanadium(III) oxide (vanadium sesquioxide or trioxide), V<sub>2</sub>O<sub>3</sub>
Vanadium(IV) oxide (vanadium dioxide), VO<sub>2</sub>
Vanadium(V) oxide (vanadium pentoxide), V<sub>2</sub>O<sub>5</sub>

Various other distinct phases include:

Phases with the general formula V<sub>n</sub>O<sub>2n+1</sub> exist between V<sub>2</sub>O<sub>5</sub> and VO<sub>2</sub>. Examples of these phases include V<sub>3</sub>O<sub>7</sub>, V<sub>4</sub>O<sub>9</sub> and V<sub>6</sub>O<sub>13</sub>.
Phases with the general formula V<sub>n</sub>O<sub>2nÃ¢ÂÂ1</sub> exist between VO<sub>2</sub> and V<sub>2</sub>O<sub>3</sub>. Called MagnÃÂ©li phases for Arne MagnÃÂ©li, they are examples of crystallographic shear compounds based on the rutile structure. Examples of MagnÃÂ©li phases include V<sub>4</sub>O<sub>7</sub>, V<sub>5</sub>O<sub>9</sub>, V<sub>6</sub>O<sub>11</sub>, V<sub>7</sub>O<sub>13</sub> and V<sub>8</sub>O<sub>15</sub>.
V<sub>3</sub>O<sub>5</sub> appears as the mineral oxyvanite.

Many vanadium-oxygen phases are non-stoichiometric.
