What keeps calcium in solution?
In other words, what prevents calcium to precipitate ?

Probably you mean what causes phosphate concentrations to get too high even so the regulations should keep them in narrow range, which is the reason why calcium precipitates and makes phosphate and oxalate stones. There are 3 types of calcium, ionized, in phosphate, citrate form and bound to proteins.
It would be either what and how regulates phosphate levels and also probably depends on the levels of the ionized calcium and what regulates that, blood pH, so hydrogen ions, bicarbonate to look as well.
