Abstract
A composition for forming a calcium phosphate type setting material comprising (1) powder comprising at least one of .alpha.-tricalcium phosphate and tetracalcium phosphate; and (2) a setting solution comprising an aqueous acidic solution having dissolved therein at least one polysaccharide selected from the group consisting of carboxymethyl chitin, glycol chitin, pullalan, high methoxy-pectin and chitosan in such an amount that the setting solution has a viscosity of 70 cp or more, and a process for producing a calcium phosphate type setting material using such a composition.

A composition for forming a calcium phosphate setting material comprising
- (1) powder comprising at least one of .alpha.-tricalcium phosphate and tetracalcium phosphate;
- and
- (2) a setting solution comprising an aqueous acidic solution having dissolved therein at least one polysaccharide selected from the group consisting of carboxymethyl chitin, glycol chitin, pullulan, high methoxy-pectin and chitosan in such an amount that said setting solution has a viscosity at room temperature of 70 cp or more.
A process for producing a calcium phosphate setting material comprising the step of mixing
- (1) powder comprising at least one of .alpha.-tricalcium phosphate and tetracalcium phosphate;
- and
- (2) a setting solution comprising an aqueous acidic solution having dissolved therein at least one polysaccharide selected from the group consisting of carboxymethyl chitin, glycol chitin, pullulan, high methoxy-pectin and chitosan in such an amount that said setting solution has a viscosity of 70 cp or more, to form a setting material.
