BIOMATERIALS, THEIR PREPARATION AND USE

摘要

A calcium oxide-silica composite biomaterial either in amorphous state or crystalline state having an average pore size, as determined by the BET method, in the range of from 0.8 nm to 20 nm, preferably from 0.8 nm to 10nm, more preferably from 0.8 to 4 nm, wherein the calcium oxide-silica content of the biomaterial is at least 80 wt %, the balance being optionally one or more other materials and wherein the molar ratio of calcium oxide to silica is at least 0.1.
