摘要: Abstract By appropriate modifications of existing precipitation methods, apatite samples formula M10(PO4)6X2 (M=Ca, Pb, Ba and X=F, OH) were prepared at 80°C. Samples characterized using X-ray diffraction, infrared, 31P NMR, SEM, chemical analysis. comparing the effect fluoride hydroxide ions on ionic conductivity measurements, it was concluded that fluorinated materials (MFAp) better conductors than other hydroxyapatites (MHAp). The F− H+ are main charge carriers, respectively, in fluoroapatite hydroxyapatite compounds. most pronounced conduction properties observed lead material. These results should provide important physico-chemical information for diffusion roles played by inhibiting dental caries.
