Abstract
A calcium phosphate granular cement contains mixed powders obtained by mixing .alpha.-type calcium tertiary phosphate or calcium quaternary phosphate with a calcium phosphate compound selected from calcium primary phosphate, calcium secondary phosphate and mixtures thereof at a Ca/P molar ratio of 1.35 to 1.49 or 1.30 to 1.90. A minimum diameter of each cement granule is 0.1 to 1.0 mm.
