| titleOfInvention | Fabrication method of Porous Calcium Phosphate Ceramics |
| abstract | The present invention relates to a method for the production of calcium phosphate, comprising: dry mixing a mixture comprising calcium and phosphorus and a pore former; Adding a binder to the mixed dry mixture and kneading the mixture; Aging the kneaded mixture; Charging the aged mixture into an extruder, and then subjecting the mixture to solid-state extrusion by applying pressure; Drying the solid extruded extrudate; Sintering the dried material; And a step of carrying and etching the sintered sintered body by an etching solution selected from the group consisting of hydrochloric acid, sodium hydroxide and nitric acid. Therefore, even if biodegradation occurs during the use of the bone structure, the porous bone substitute having a high porosity and pore size and a three-dimensionally well-connected pore shape can be easily produced while retaining the mechanical strength for a certain period of time. In particular, it is possible to make the skeletal structure of the porous body dense and increase the mechanical strength while increasing the interconnectivity of the porous body pores. |
