Notes:
Porous HAp scaffolds have been prepared by using the slurry including HAp and magnesiabased on the replication of polymer sponge substrate. The influence of HAp and MgO content inslurry on the pore morphology and size, and density, porosity, and mechanical strength of porous HApscaffolds was investigated. The obtained scaffolds with average pore sizes ranging 150 to 300 μm hadopen, relatively uniform, and interconnected porous structure regardless of HAp and MgO content. Asthe MgO content increased, the pore network frame of scaffolds became to be relatively stronger,even though the pore size was not much changed. The compressive strength of the scaffolds increasedrapidly with the increase of MgO content at a fixed HAp content because of increasing the pore wallthickness and density of the scaffolds. As a result, the porosity, density, and compressive strength ofthe porous HAp scaffolds scaffolds prepared by the sponge method were significantly affected by theaddition of MgO
