PROBLEM TO BE SOLVED: To provide a calcium phosphate cement curing soln. and a cured object compsn. characterized by that the compsn. for a cured object is hardly collapsed even if allowed to fill immediately after kneaded with a powder agent. SOLUTION: A calcium phosphate cement curing soln. composed of an aq. soln. containing 0.5-10wt.%, especially, 0.8-5wt.%, further, 1-4wt.% of a pectin substance such as pectin, pectic acid or pectinic acid is obtained. The pH of this curing soln. is pref. set to 3-5, especially 3.2-3.6 and the viscosity thereof is pref. set to 200dPa.s or less, especially, 20dPa.s, further, 0.5-5dPa.s. As a powder agent, tetracalcium phosphate, calcium hydrogen phosphate, α- tricalcium phosphate, β-tricalcium phosphate and hydroxyapatite can be used. As this powder agent, especially, it is pref. to together use tetracalcium phosphate and calcium hydrogen phosphate in an about equimolar ratio. |
