This specification covers chemical and crystallographic requirements for biocompatible beta-tricalcium phosphate for surgical implant applications. Elemental analysis for calcium and phosphorus will be consistent with the expected stoichiometry of beta-tricalcium phosphate. The calcium and phosphorus content shall be determined using a suitable method such X-ray fluorescence. A quantitative X-ray diffraction analysis shall indicate a minimum beta-tricalcium phosphate content of 95 % as determined using powder diffraction method. The analysis of other trace elements may be required, based on the conditions, apparatus, or environment. It is recommended that all metals or oxides present in concentrations equal or greater than 0.1 % be noted in material descriptions.

1. Scope

1.1 Thisastm specification covers chemical and crystallographic requirements for biocompatible beta-tricalcium phosphate (β-TCP) for surgical implant applications. For a material to be identified as medical grade beta-tricalcium phosphate, it must conform to this specification (see Appendix X1).

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
