Effect of Mechanical Activation of Powders on the Sintering of Calcium Carbonate-Based Ceramic Materials Containing Carbonated Hydroxyapatite

摘要

Calcium carbonate-based materials containing carbonated hydroxyapatite are promising as materials for replacing and restoration of bone defects [1]. The key technological drawback of these materials is low-temperature thermal decomposition of calcium carbonate, which prevents sintering [2, 3]. This accounts for low strength of materials and precludes using them as implants bearing mechanical load [4]. The activity of ceramic powders toward sintering can be enhanced by mechanical activation (MA) [5].
