Phase composition and in vitro bioactivity of porous implants made of bioactive glass S53P4
Abstract
This work studied the influence of sintering temp. on the phase compn., compression strength and in vitro properties of implants made of bioactive glass S53P4. The implants were sintered within the temp. range 600-1000 °C. Over the wholetemp. range studied, consolidation took place mainly via viscous flowsintering, even though there was partial surface crystn. The mech.strength of the implants was low but increasedwith the sintering temp., from 0.7 MPa at 635 °C to 10 MPa at 1000 °C. Changes in the compn. of simulated body fluid (SBF), the immersionsoln., were evaluated by pH measurements and ion anal. using inductivelycoupled plasma optical emission spectrometry. The development of acalcium phosphate layer on the implant surfaces was verified usingSEM-electron-dispersive X-ray anal. When immersed in SBF, a calciumphosphate layer formed on all the samples, but the structure of thislayer was affected by the surface cryst. phases. Hydroxyapatite formedmore readily on amorphous and partially cryst. implants contg. both primary Na<sub>2</sub>O·CaO·2SiO<sub>2</sub> and secondary Na<sub>2</sub>Ca<sub>4</sub>(PO<sub>4</sub>)<sub>2</sub>SiO<sub>4</sub> crystals than on implants contg. only primary crystals.
