Disclosed herein is a biodegradable and bioactive glass-ceramic fabricated by mixing a slowly biodegradable glass-ceramic and a highly biodegradable glass-ceramic in a predetermined mixing ratio wherein the bioactivity is maintained to be constant, and the biodegradation rate is controlled by the mixing ratio. The biodegradable and bioactive glass-ceramic is fabricated from a composition consisting of calcium oxide (CaO), silica (SiO), boron oxide (BO), magnesium oxide (MgO), calcium fluoride (CaF) and phosphorus pentoxide (PO).

Biodegradable and bioactive glass-ceramics, and method for fabricating the same

Disclosed is a method for producing a transparent and homogenized polymeric sol of a calcium phosphate compound, containing apatite and having excellent wettability and bioactivity, according to a sol-gel synthesis, and a method for coating the polymeric sol on a metal implant, in which the polymeric sol is coated on the metal implant and then heat-treated to form a dense coated layer strongly bonded to the metal implant. The polymeric sol is obtained by process of preparing a calcium salt solution, containing calcium ethoxide dissolved in organic acid, and a phosphate solution, containing triethyl phosphite or triethyl phosphate dissolved in the organic acid, mixing the calcium salt solution with the phosphate solution to produce a mixed solution, and aging the mixed solution.

Disclosed herein are a self-foamed porous ceramic composition and a method for making a porous ceramic using the self-foamed porous ceramic composition. The self-foamed porous ceramic is obtained by fabricating a glass consisting of 41&#x2dc;47 mole % of calcium oxide (CaO), 41&#x2dc;47 mole % of silica (SiO) and 6&#x2dc;18 mole % of borate (BO), pulverizing the glass into a finely-divided glass powder having an average particle size of 1&#x2dc;10 &#x3bc;m, molding the glass powder, and sintering the molded glass powder.
