Characterization of
silica glasses, sintered under [Cl.sub.2] ambients.
Although the capillary effect convincingly explains the formation mechanism of water droplets from a tap and/or bubbles through a water flow, this effect does not appear to apply to the cavity formation mechanism of a fiber fuse owing to the anomalously high viscosity of the
silica glass [22, 32].

The ultrasonic vibration assisted micro end grinding of
silica glass is conducted on a manual developed machine tool, as is shown in Figure 7, which is built for the purpose of realizing three crucial motions in UAMEG: workpiece ultrasonic vibration, high speed grinding wheel rotation, and high-accuracy feed motion.
At the centre of the attention of this team was a mysterious black pebble found years earlier by an Egyptian geologist in the area of the
silica glass.
While
silica glass was traditionally made by melting and rapidly cooling high-purity quartz, Spectrosil is made by feeding silicon tetrachloride gas into a hydrogen-oxygen flame to produce a glass of higher purity and transparency.
1 is devoted to three-layer fiber waveguide sensors which consist of a
silica glass substrate (S), a metal layer (M) and an aqueous media (A) denoted as SMA sensor or chalcogenide glass substrate (Ch), and a metal layer (M) and aqueous media (A) denoted as ChMA sensor.
Figure 2 provides an example of such a parallel set of ESR and optical isochronal anneal sequences recorded for a germanium-doped
silica glass initially x-irradiated at ~100 K and annealed for 5 minutes at each sequence of higher temperatures [5, 6].
Meltings were made in clay crucibles in which ZrO2 was progressively substituted in a selected soda lime
silica glass. Durability of each sample was determined by weight loss method.
The modulus of elasticity is higher than the glass fiber and the coefficient of thermal expansion is low enough to be equal to
silica glass with 1X[10.sup.7]/[degrees]C.
