Method for enrichment of bioactive glass, involves processing ion exchange and heat treatment, where bioactive glass is immersed in reaction medium of calcium material
NOVELTY – The method involves processing ion exchange and heat treatment, where bioactive glass is immersed in a reaction medium of calcium material. The calcium material is fused under inert atmosphere and at temperature below glass transition temperature of the bioactive glass. Surface of the bioactive glass is exposed to a heat source for a short period of time, where another surface of the bioactive glass is covered by a thermal insulating material. USE – Method for enrichment of bioactive glass for preparation of bone implants. ADVANTAGE – The method involves processing ion exchange and heat treatment, where bioactive glass is immersed in a reaction medium of calcium material, and hence ensures improved mechanical characteristics of the glass. DETAILED DESCRIPTION – An INDEPENDENT CLAIM is also included for an enriched bioactive glass. DESCRIPTION OF DRAWING(S) – The drawing shows a graphical representation that depicting result of differential thermal analysis and thermal gravimetric analysis of bioactive glass. (Drawing includes non-English language text).
