英文摘要 | Titanium dioxide is added into calcium phosphate bio-glass (CPG) to have crystalline phases of titanium phosphoric (TiPb....Ob.. ) and calcium phosphoric (CaPb....Ob.. ) on its surfaces. The bio-glass synthesis with the addition CPG and TCPG were immersed in Hanks' solution for two days before soaking in the mixed solutions of (NHb.. )b....HPOb.. and Ca(NOb.. ) b.... at 70B0. Crystalline layers of titanium phosphoric were observed on the surfaces of TCPG from immersing in hanks' solution. After which calcium pyrophosphate appeared on the second step of soaking process from the calcium ion contained solutions. Due to the absence of crystalline phases on the surfaces of CPG specimen, it can be deduced that the addition of titania (TiOb....) causes the hydroxyapatite formation on the surface of bio-glass. |
