Industrial production is by reaction of a fluoride with a metaphosphate. He proposed that ATP transfers phosphate through a reactive monomeric metaphosphate species. A metaphosphate ion is an oxyanion that has the empirical formula . Barium metaphosphate is an inorganic substance with the molecular formula Ba(PO). Uranyl metaphosphate is a compound of uranium, phosphorus, and oxygen. Here, a proportion of fluorides is stabilized with a metaphosphate, with addition of titanium dioxide. When heated further, MKP decomposes, by loss of water, to potassium metaphosphate, , at .
