Preparation of HAp whiskers with or without Mg ions and their effects on the mechanical properties and osteogenic activity of poly(,-lactide)

Hydroxyapatite whiskers (HAp-Ws) and magnesium-substituted hydroxyapatite whiskers (Mg-HAp-Ws) with 1, 3, and 5 mol% magnesium (Mg) ion substitution contents were successfully prepared by the hydrothermal method. The incorporation of Mg ion into the HAp-Ws led to a morphology including a combination of whiskers and particles and a decrease in the crystal interplanar spacing. Then, the HAp-Ws and Mg-HAp-Ws were further introduced into a...
