Abstract:
1. A method of producing a porous tricalcium phosphate net-shaped material having an intended final shape, comprising: preparing a powder reactant mixture comprising calcium oxide powder and phosphorus pentoxide powder, wherein a mole percent ratio of said calcium oxide powder to said phosphorus pentoxide powder allows the powdered reactant mixture to form tricalcium phosphate upon subsequent combustion; forming said powder reactant mixture into said intended final shape by placing said powder reactant mixture into a combustible or noncombustible die having said intended final shape and compressing said powder reactant mixture to form a formed reactant mixture; if said die is noncombustible, removing said formed reactant mixture from said die; and heating said formed reactant mixture to at least an ignition temperature of said formed reactant mixture to produce said porous tricalcium phosphate net-shaped material by a combustion synthesis reaction, wherein said porous tricalcium phosphate net-shaped material is selected from the group consisting of an alpha tricalcium phosphate, a beta tricalcium phosphate and mixtures thereof.
