The biocompatibility and bioactivity properties of hydroxyapatites (HAs) modified through lithium addition were investigated. Hydroxyapatites obtained from bovine bone were mixed with lithium carbonate (Li), in the proportions of 0.25, 0.50, 1.00, and 2.00%wt, and sintered at 900◦, 1000◦, 1100◦, 1200◦, and 1300◦C, creating LiHA samples. The osteoblast culture behavior was assessed in the presence of these LiHA ...
