PURPOSE:To obtain the curable material which yields cured matter having high hardness when respective components of materials are kneaded and rested to cause hydration self-curing and to obtain the cured matter converting to apatite having excellent bioaffinity upon lapse of time and which allows a change in curing time within a range from 5 minutes to about several hours at a relatively low temp. around the temp. of a living body by adjusting the amt. of the acids to be added, the amt. of a neutralizer, etc. CONSTITUTION:This curable material contains hydration self-curing calcium phosphate contg. calcium which is a curable material having a self-curing property and phosphorus at Ca/P=1.3 to 2.0 ratio by atomic ratio, at least one kind of the neutralizers selected from a fluoride hardly soluble in water, at least one kind of the fluorides soluble in water selected from sodium fluoride, acidic sodium fluoride, potassium fluoride and acidic potassium fluoride, acid, sodium hydroxide, and postassium hydroxide and water, and has (na+K)/F=0.2 to 40 ratio by respective atoms of the sodium, postassium and fluorine of at least one kind of the above-mentioned fluorides soluble in water and the above- mentioned neutralizers. |
