Apatite glass-ceramic useful for making dental materials comprises a glass phase and a phosphate- and fluorine-free silicate-based oxyapatite phase

摘要

Apatite glass-ceramic (I) comprises a glass phase and a phosphate- and fluorine-free silicate-based oxyapatite phase. An independent claim is also included for producing (I) by mixing the necessary components, fusing the mixture to form a glass melt, converting the melt into granules, optionally comminuting the granules to a powder with an average particle size of 1-500 mu m, and firing the granules or powder at 700-1200[deg]C for 0.5-6 hours.
