Description
|
This Standard Reference Material (SRM) is intended for use in evaluating the physical and chemical properties of apatites with biological, geological or synthetic origins. The calcium to phosphorus (Ca/P) molar ratio for SRM 2910b is consistent with the theoretical Ca/P molar ratio of 1.67 for hydroxyapatite and a compositional formula of
Ca10(PO4)6(OH)2.
|
Package |
A unit of SRM 2910b consists of a 2 g bottle of hydroxyapatite powder. |
