Video of the week: Richard Brow on glass strength, phosphate glasses and the continuing allure of glass materials and applications

Published on August 18th, 2010 | By: pwray@ceramics.org

Richard Brow will tell you he likes everything about glass science, art and
processing. Brow, an ACerS Fellow and Curator’s Professor of Ceramic
Engineering at Missouri University of Science & Technology in Rolla,
Mo., discusses his fascination with glass and delves into two specific
areas: tapping into the theoretical strength of glass, and the special
field of phosphate glasses.


Brow recently coauthored “The Strength of Silicate Glasses: What Do We Know, What Do We Need to Know?” in the new ACerS publication, the International Journal of Applied Glass Science.
He explains that scientists and engineers know that glass can be made
much stronger and that a great deal of research is being done in this
field. He notes that even small improvements would translate into
significant benefits in architecture and construction, glass fibers for
wind turbines, packaging, electronics and bioactive glass implants.


He also discusses his research into phosphate glass materials and
applications. Most glass-related research and applications focus on
silicate glasses, but phosphate glasses can make wider use of special
doping materials such as Rare Earths oxides  that can impart special
optical and thermal properties to glass. Phosphate glasses can be
processed at lower temperatures than silicate glasses.
