Extraordinary Boride Ceramics

Extraordinary boride ceramics attract a great interest due to the demand for
 high-performance materials important to many security related advanced
 technologies. Boron tends to form clusters in which B12 icosahedra or
 cubooctahedra are common structural units. Within B-clusters, the valence
 electron density is high, so boron-rich solids feature strong covalent bonding
 and correspondingly high melting point, high hardness, low compressibility, yet
 light weight and low coefficient of thermal expansion. These properties make
 borides good candidates for use under extreme conditions where other materials
 fail, including: abrasives; cutting tools; lightweight armor; fiber reinforcement;
 neutron shielding; nuclear reactor control rods; sand-blaster nozzles; turbines
 blades; thermal protection systems (TPS) for rockets; electron emitting cathodes
 for electron microscopy; thermocouples; thermoelectrics; and many other
 amazing applications. Boron has high affinity for transition- and rare-earth
 metals, which form many interesting borides. Metal atoms provide additional
 electrons that stabilize structures, resulting in new properties. Very few borides
 have a band gap above 2 eV, so most are darkly colored or opaque and
 unsuitable for optical applications, however a few found an innovative optical
 application as protective transparent thin films.


Research topics of the Workshop are as follows:

- synthesis of new boride ceramics
- boride nanocomposites
- boride thermoelectric conversion materials
- boride superconductors
- ultra high temperature ceramics
- lightweight advanced ceramic armor
- mechanical, thermal, optical, and electrical behavior of boride polycrystals
- methods to process boride nanomaterials
- boron rich solids: science and technology
