THE METHOD OF PREPARING CA/P MOLE RATIO CONTROL OF BONE GRAFT BIOACTIVE BIPHASIC CALCIUM PHOSPHATE COMPOSITIONS

摘要

PURPOSE: hydrowyapatite the and β tricalcium phosphates that production bioactivity calcium phosphate composition mixed transplantation is provided to characteristic adjust the composition of absorptivity. ;CONSTITUTION: production bioactivity calcium phosphate composition is for transplanting following steps: synthesis co-precipitated materials are using calcium (NO3) 24H2O and (NH4) 2HPO4 as raw material; It adulterates Ca (NO3) 24H2O and (NH4) 2HPO4 and matches Ca/P molar ratios, obtain solution respectively to material; It is inserted into Ca (NO3) 24H2O solution and deionized water and distilled water is added, slowly apply (NH4) 2HPO4 solution and be added in mixture; Stirring is completely dissolved suspension, and ammonium hydroxide is added to the mixture, adjusts the pH of mixture 9.9-10.1 co-precipitation; And the dry solution, 800-950 degree is 1-3 to the solution before being calcined. ;The 2013 of copyright KIPO submissions
