The invention relates to a synthetic bone material and a process for making the same. The synthetic bone material may comprise multiple phases of calcium phosphate. Another aspect of the invention is a porous filter, and the method of making the same, and wherein the porous filter is substantially similar to the process for forming the synthetic bone material.

Combustion synthesis of calcium phosphate constructs and powders doped with atoms, molecules, ions, or compounds

Methods for producing porous tricalcium phosphate net-shaped material are provide. The methods involve preparing a reactant mixture comprising calcium oxide and phosphorus pentoxide in a mole percent ratio that allows the mixture to form tricalcium phosphate upon combustion thereof, forming this mixture into a desired final shape in a die with compression, and carrying out a combustion synthesis therewith. Net-shaped TCP materials of the combustion synthesis, comprising alpha tricalcium phosphate or mixtures of alpha and beta tricalcium phosphate, are optionally further treated to effect transition of the alpha phase to the beta phase. The net-shaped TCP materials can have a uniform or non-uniform porosity.
