Fig. (8.11): ESEM micrograph of the surface of glass fibre of composition MOF005ii<br />

(70TeO2-10Na2O-20ZnF2 mol. %), mounted on a carbon tab.<br />

These crystals, which are nodular when imaged on the surface of the fibre, are of the<br />

same order of magnitude (≈ 2 µm) as the crystals seen in cross-section (figs. (8.7) to<br />

(8.10)).<br />

Crystals<br />

Fig. (8.12) shows an ESEM micrograph of a snowflake shaped crystal away from the<br />

surface in the glass fibre of composition MOF005ii (70TeO2-10Na2O-20ZnF2 mol. %).<br />

The fibre was mounted end on in epoxy resin, and polished back.
