Abstract
Methods for preparing a tricalcium phosphate coarse particle composition are provided. Aspects of the methods include converting an initial tricalcium phosphate particulate composition to hydroxyapatite, sintering the resultant hydroxyapatite to produce a second tricalcium phosphate composition and then mechanically manipulating the second tricalcium phosphate composition to produce a tricalcium phosphate coarse particle composition. The subject methods and compositions produced thereby find use in a variety of applications.
Claims19
A method of making a tricalcium phosphate coarse particle composition, said method comprising:
- (a) converting an initial tricalcium phosphate particulate composition to hydroxyapatite;
- (b) sintering said hydroxyapatite to produce a second tricalcium phosphate composition;
- and
- (c) mechanically manipulating said second tricalcium phosphate composition to produce a tricalcium phosphate coarse particle composition, wherein said coarse particles comprise sodium in an amount ranging from 1500 to 2500 ppm.
A tricalcium phosphate coarse particle composition comprising tricalcium phosphate particles ranging in size from 38 to 212 μm, wherein said particles comprise sodium in an amount ranging from 1500 to 2500 ppm.
