Abstract
The invention relates to a preparation method of superfine calcium phosphate powder. The preparation method comprises the following steps: (a) adding calcium chloride solution to calcium dihydrogen phosphate powder by a molar ratio of calcium to phosphate of 1.5 to 1, and stirring and mixing the mixture uniformly; (b) boiling the mixture of step (a) after being uniformly stirred for 24 hours at 100 degrees, wherein the pressure intensity of the interior part of a reactor is 0.4 to 0.6 MPa; (c) filtering the reacted mixture of step (b), drying the mixture, and finally calcining the mixture for half an hour at 900 degrees to obtain nanometer calcium phosphate powder. The technical scheme provided by the invention has the advantages of simple preparation method and low cost.
Description
Technical field
The present invention relates to chemical field, particularly relate to the preparation method of a kind of ultra micro calcium phosphate powder of field of new.
Background technology
Tricalcium phosphate is widely used in artificial bone, electroceramics, Bone China etc. owing to having the main component of human bone.At present batch production adopts solid reaction process, scorification and chemical method precipitations etc., but its technique adopts ball milling or lime etc. more, and slightly or complex process, cost is high for institute's particle of producing.
Because the defect that the preparation method of above-mentioned existing tricalcium phosphate exists, practical experience and the expertise of the inventor based on being engaged in this type of product design manufacture and enriching for many years, and the utilization of cooperation scientific principle, actively research and innovation in addition, to founding a kind of preparation method of new ultra micro tricalcium phosphate powder, can improve the preparation method of general existing tricalcium phosphate, make it have more practicality.Through constantly research, design, and after repeatedly studying sample and improving, finally create the present invention who has practical value.
Summary of the invention
Main purpose of the present invention is, overcome the defect of preparation method's existence of existing tricalcium phosphate, and a kind of preparation method of new ultra micro tricalcium phosphate powder is provided, technical problem to be solved is to make that preparation method is simple and cost is low, is very suitable for practicality.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of preparation method of ultra micro calcium phosphate powder who proposes according to the present invention, wherein this preparation method comprises the following steps: (a), calcium chloride solution is joined in monocalcium phosphate powder taking calcium phosphorus mol ratio as 1.5:1, be uniformly mixed; (b), the mixture after stirring in step (a) is boiled 24 hours in the time that 100 spend, the pressure in reactor is 0.4-0.6MPa; (c), reacted mixture in step (b) is filtered, dry, finally in the time that 900 spend, calcine 0.5 hour, obtain nano-calcium phosphate powder.
Wherein the calcium chloride solution of one of reactant source is to prepare the by product obtaining in alumina whisker, and the preparation method's of this alumina whisker number of patent application is 201410118888.9.
By technique scheme, the present invention at least has following advantages: this research is prepared tricalcium phosphate nano powder by the hydrolysis method of calcium chloride and monocalcium phosphate cheaply, and technique is simple, and cost is low.
