Fibre drawing; MDO 347 Crystal Fig. (8.12): ESEM micrograph of a snowflake shaped crystal in the glass fibre of composition MOF005ii (70TeO2-10Na2O-20ZnF2 mol. %), mounted end on in epoxy resin, and polished back. EDX analysis was performed at point Q (crystal) and R (glass) on fig. (8.12). Fig. (8.13) shows the EDX spectra from points Q and R. Q R Glass
8. Fibre drawing; MDO 348 Fig. (8.13): EDX spectra from points Q (⎯ crystal) and R (⎯ glass) from fig. (8.12). It can be seen from these EDX spectra (fig. (8.13)) that the crystal contains less oxygen and tellurium, and more fluorine and sodium than the glass. The amount of zinc is approximately the same in both the crystal and the glass. The EDX technique will sample an area similar to the diameter of the beam (10 µm). The crystal in fig. (8.12) is around 2 µm in diameter, therefore, inevitably some glass will also have been sampled. The quantification from EDX in cases such as this therefore can only be used to obtain relative amounts of elements present, i.e. the crystalline phase is fluorine and sodium rich, and oxygen and tellurium deficient, compared to the glass. Fig. (8.14) shows an ESEM micrograph of four crystals in the glass fibre of composition MOF005ii (70TeO2-10Na2O-20ZnF2 mol. %). The fibre was mounted end- on in epoxy resin, and polished back.
