Comparison of hydroxyapatite ceramics and hydroxyapatite/borosilicate glass composites prepared by slip casting

Borosilicate glass powder with a softening point of 821 °C was prepared by crushing Pyrex® borosilicate glass fragments. Hydroxyapatite (HA) ceramics and HA/borosilicate glass (50 wt.%) composites were prepared by slip casting. The influence of borosilicate glass on the densification and phase change of hydroxyapatite was studied over sintering temperatures from 500 to 1200 °C. It was found that the borosilicate glass inhibited the decomposition...
