    The answer should be no.

    See the followings from

    http://en.wikipedia.org/wiki/Phosphate

    Many phosphates are insoluble in water at standard temperature and pressure, except for the alkali metal salts.

    As calcium belongs to Group II, its salt formed with phosphate ion should be ALKALINE EARTH METALS SALTS. Only those Group 1 elements (Na, K , Rb etc.) will form alkali metal salts.

    Hope it helps.
