It has chemical formula Na₄V₂O₇.

Zinc pyrovanadate with a good yield was prepared successfully with a short reaction time (few minutes) at normal pressure by using a simple method of preparation which consists of mixing a boiling solution of vanadium oxide (obtained by reacting V₂O₅ with few millilitres of 30 vol.% H₂O₂ following dilution with distilled water) with zinc nitrate solution. The zinc pyrovanadate precipitates at pH 5.6 after adding the appropriate amount of ammonium hydroxide.
