Boron Oxide plays a key role in numerous glasses of high technological importance, yet its role in glass structure is far from clear. Indeed, in recent years there have been serious chal lenges to previous structure concepts for both crystalline an

Electrical de fields applied through electrodes on either side of a slow-running crack in soda-lime-silica glass resulted in a deviation of the crack plane and in delayed deceleration, arrest, and healing. In some cases crack closure occurred while s

Chill checks of controlled depth were produced in soda-lime-silica glass, and an optimum humidity of 30 kPa (300 mbar) water vapor pressure was found to heal these checks in an annealing cycle. Critical factors were found to be a fluxing effect, havi

The finite element technique was used to trace the sequence of bond breakages in a precracked ideal MgO crystal under dynamic loading. The crack velocity was then calculated from the time interval between the breaking of successive bonds. There was a

Thin films of gold were deposited by evaporation onto glass surfaces generated by slow fracture in a vacuum. Such films characteristically show an agglomerated or coalesced structure. Deliberate contamination of the substrate and growing films with O

Crack growth in glass plates, up to supercritical velocities, was produced by controlled strain, velocity being measured continuously by superimposing a tuned-frequency sonic signal during cracking. Cracks, which were accelerated to supercritical vel

Stress distributions calculated for thin disks having a cylindrical inclusion were found to agree with those measured for glass specimens cooled to room temperature after they were sealed. Maximum circumferential stress in the sheath was independent
