It probably has something to do with the fact that it doesn't easily dissolve.

Phosphorus in general is a whore that clings to everything. Phosphate won't let go of that calcium until it finds another man to leech on.

The ionic charge means they find it very difficult to form stable hydration spheres to separate them. Probably has more to do with the fact that there is a 2+ calcium in solution that doesn't really like water. It's not a covalent bond but an ionic one.
