ReferenceJournal of Solid State Chemistry (1994) 108, 68-72 Link XRef SCOPUS Google CompoundH4 Ca8.86 O26 P6 - [Hydroxylapatite] Calcium phosphate hydrate (8.9/6/2) [A6B9X26] [hP45] [i h4 f e]  Cell9.46(1), 9.46(1), 6.88(1), 90., 90., 120.P63/M (176) V=533.21 RemarksR=0.090000 : DEF MIN =Hydroxylapatite : PDF =9-432 : Deviation of the charge sum from zero tolerable. Calculated density unusual but tolerable. The coordinates are those given in the paper but the atomic distances do not agree with those calculated during testing.The coordinates are probably correct. The Ca2 position contains some Na Position of (O H) group was not refined.
