説明

Co-ordination of Al-ions and the bond length of Al-O in high alumina glass were determined by the radial distribution function analysis using X-ray diffraction technique. A silica glass, two kind of Al2O3-SiO2-Na2O glasses and an Al2O3-SiO2-MgO glass were employed for the analysis.<br>The radial distribution function of these test pieces were computed with the diffracted intensities which were counted with fixed time method by scintillation detector plus pulseheight analyzer applying filtered Cu and Mo radiations. The bond length between the atoms were estimated from radial distribution curves and the results obtained were as follows:<br>Si-O 1.60Å Si-Si 3.15Å<br>Al-O 1.73Å Al-Al 3.30Å<br>Mg-O 1.93Å<br>The co-ordination numbers of Al-ions evaluated from radial distribution function analysis as follows:<br>These corresponded to 5.1-fold when the ratio of Al2O3/Na2O in the glass was 1.63, and 4.6-fold when the ratio was 0.87.<br>These values were agreed well with the values obtained from the X-ray fluorecence study.
