Dissolution behavior of monovalent ion doped β -tricalcium phosphate

Abstract

The effects of doping the monovalent ion (Li⁺, Na⁺, K⁺ions) in β -tricalcium phosphate ( β -TCP) on these solubility were investigated by dissolved test in distilled water and saline solution. The order of the leaching rate of Ca²⁺ ion was Li⁺ ion doped β -TCP< Na⁺ ion doped β -TCP< K⁺ ion doped β -TCP< β -TCP. From these results, the leaching rate of Ca2+ ion of the monovalent ion doped β -TCP would be related to these lattice constants. In addition, the crystal phase and lattice constant of all the filtered precipitates after dissolved test unchanged regardless of the immersing day.
