INVESTIGATION OF SINTERING FEATURES OF CERAMIC MATERIALS BASED ON HYDROXYAPATITE AND ITS SUBSTITUTED FORMS

INVESTIGATION OF SINTERING FEATURES OF CERAMIC MATERIALS BASED ON HYDROXYAPATITE AND ITS SUBSTITUTED FORMS

Stoichiometric and fluorsubstituted hydroxyapatite powders with increased sintering activity (the initial compaction temperature is 600 °C) were synthesized by precipitation from solutions. Properties of synthesized powders and ceramics after firing were investigated. It is shown that the introducti...
