| titleOfInvention | Production method for calcium phosphate nano- particles with high purity and their use |
| abstract | The present invention provides a continuous process for producing calcium phosphate nanoparticles in a network mixer or static mixer reactor, fed by a calcium solution, a phosphorous solution and an alkaline solution and, optionally, one solvent or dispersing agent. The proposed process enables the micromixing control, which is essential to form nanometric structures, but it is also a determining factor in the crystals purity, crystallinity and morphology. The reactants distribution scheme at the inlet of the reactor and along the reactor, performed continuously or varying in time, is also a crucial factor to programme the pH of the reactant media along the reactor. The calcium phosphate nanoparticles suspension that exits the reactor can be submitted to further aging, ultra-sounds, separation, drying, sintering and milling processes. Some calcium phosphates are considered biomaterials, used as: food additives and nutritional supplements; bone graft for bone replacement, growth and repair; biocements and coating of metallic implant. Some of the most recent applications include their use in cosmetics, toothpaste and in esthetical treatments for diminishing wrinkles by stimulating conjunctive tissue formation. |
