23 Jul Method for preparing fluorapatite crystal whisker in-situ reinforced porous tricalcium phosphate biological ceramics
Abstract
The invention relates to a method for preparing fluorapatite crystal whisker in-situ reinforced porous beta-tricalcium phosphate biological ceramics, and belongs to the technical field of the preparation of biological ceramics. The method is characterized by comprising the following steps of: weighing beta-tricalcium phosphate, bioglass and ammonium fluoride (or fluorine salts such as sodium fluoride and the like) serving as raw materials in a mass ratio of (65-85):(10-30):(0.25-1.5), and performing solid-phase reaction at a high temperature to prepare high-strength fluorapatite crystal whisker in-situ reinforced tricalcium phosphate porous biological ceramics. The method has the advantages that toughness is enhanced by introducing fluorapatite crystal whiskers and the strength of a substrate is enhanced, and the biological ceramics are mainly used for the field of the repair of bone tissue engineering at bearing positions or other positions.
