See the for a list of tungstates. In fact, polyvanadates are more similar to the oxomolybdates and tungstates. Tungsten is similar to molybdenum and forms many tungstates containing 6 coordinate tungsten. Double tungstates of the form AB(WO) are predicted to exist in the langbeinite form. Salts of tungstic acid are tungstates. Almost all useful tungsten ores are tungstates. Crystal tungstates are used as scintillation detectors in nuclear physics and nuclear medicine.
