Did anyone respond to the statement that bicalcium phosphate does not exist?
I missed several days of Clayart and so might not have seen a reply.
Anyway, calcium phosphate with just two calcium atoms per molecule does
indeed exist, except that its name is dicalcium pyrophosphate (Ca2P2O7). It
is available, anhydrous, from Sigma (800-325-3010) for $9.20 per 500 g.

Hey Stuart,
Don't remember that bit of heresy - but there is also Monocalcium Phosphate
Ca(H2PO4)2.H2O with 55.5% P205 and 17.3 CaO by weight.
