| Abstract: | Hydroxyapatite ceramics with controlled porosity and pore size were prepared by adding PMMA as pore－ forming agent(PFA). Samples were prepared with total pore volumes changing from 20％ to 50％ . The pore structure ,pore size distribution and characteristics were studied, and it was found that the hydrox－ yapatite ceramics with controlled－ porosity could prepared by adding PMMA as PFA . As well, the factors influencing porosity and mechanical strength of porous ceramics were discussed. |
