Fluorapatite (Ca5(PO4)3F) Procurement
I have a reaction I've been investigating that requires the use of fluorapatite, or some other similar compound of the form Ca5(PO4)3X, where the 'X'
is a simple anion with a 1- charge. Does anyone know where I could buy some at a reasonable purity? All of the suppliers I've checked are only
shipping to labs.

You may wish to consider some methods of preparation. For example:
10Ca(OH)2 + 6H3PO4 = Ca10(PO4)6(OH)2↓ + 18H2O

Hydroxylapatite, where X = OH-, is a major component of bones and teeth. Fluoride substitution for the hydroxyl group in this mineral
is why there's fluoride in your toothpaste and water. In olden times, these would have been in plentiful supply and possibly even of adequate purity.
That wikipedia page has the more modern answer to your question, which is that hydroxylapatite is available as a food supplement, a calcium source
derived from bone meal. (FWIW, that was news to me.)
