Abstract

The main difficulty in fabricating ceramic materials based on hydroxyapatite is their high sintering temperature. Potassium feldspars, low-melting leucite glass, and synthetic alkali-containing compounds were investigated as compounds that increase the amount of melt for improving the sintering process. The effect of alkali-containing compounds on phase-formation processes occurring during sintering of compositions based on hydroxyapatite - fluorite mixtures is examined.
