Synthetic hydroxyapatite was fabricated into a white translucent polycrystalline ceramic that displays the hardness of natural apatite. The mineral composition of this product after sintering was chiefly dehydrated hydroxyapatite. In addition, a portion of the apatite was converted into α-whitlockite. Because of the similarities among the mineral compositions of bone and teeth and this ceramic, it offers prospects for implant prosthetic devices.
