Abstract: The present invention provides a process of initiating a self-propagating reaction with a coherent radiation source, which comprises mixing the chemical reactants, and contacting the chemical reactants by the coherent radiation, more specifically, the coherent radiation source may be a laser.

Abstract: 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.

Abstract: A method for making high purity, multiphasic calcium phosphate powders using an Auto-Ignition Combustion Synthesis (AICS) reaction of a calcium salt, a phosphate salt and a fuel is provided. In the method provided, energy released from the AICS reaction between the calcium salt, phosphate salt and fuel ignites at temperatures much lower than the actual phase transformation temperatures and reaches a high temperature rapidly enough for synthesis of the desired product to occur, without the requirement for coprecipitation, an external heat source for calcination and/or additional steps for removing undesired precursors from the desired final product.

Abstract: The present invention is generally directed to a method for the production of tissue implants and prosthetics, including but not limited to orthopedic implants and prosthetics which have a controlled and directional gradient of porosity moving through all or one or more portions of the implant, as well as the implants produced by such a method. The non-uniform porosity gradient may be linear or more complex, and is preferably produced to have a continuous gradient within the desired regions. The desired effect is to create an implant which more closely mimics the natural structure of bone, and which improves the quality of the bone growth that occurs within the implant.
