“Elastic Modulus of Gelcast Cellular Ceramics at High Temperatures”
The elastic modulus of alumina cellular samples with various porosities produced by gelcasting foamed suspensions was measured at room and high temperatures, and the results were compared with a novel equation that describes the effect of porosity and temperature on elastic modulus.
F.S. Ortega, J.A. Rodrigues and V.C. Pandolfelli

 

“Synthesis of Solid-Oxide Fuel Cells Using Microwave Sintering”
Dense 8-mol%-Y2O3-stabilized ZrO2 solid-oxide fuel cell electrolytes were prepared using microwave sintering and were compared with those prepared using conventional sintering.
S. Takahashi, S. Suda, K. Jono, K. Kawahara and A. Doi

“Porous Fibrous Mullite Bodies”
A porous mullite body that had no drying or firing cracks was prepared using rapid fluid infiltration into a textile template structure.
S.M. Naga, A.A. El-Maghraby and A.A. El-Rafei; T. Khalifa; P.Greil; and N. Ibrahim

 

“Advanced Melting Technology Delivers Improved Performance”
Convective glassmelting heat-transfer technology has been applied successfully in container-glass and CRT panel- glass manufacturing facilities.
Neil G. Simpson

 

“Industrial Applications of Advanced Spark Plasma Sintering”
Spark plasma sintering has been used to manufacture high-wear-resistant and hard WC/Co/Ni dense ceramics, including aspheric glass-lens molding dies, sandblasting nozzles and extruding machine screws.
Masao Tokita

 

“Effect of Oxides on Decreasing Melt Viscosity and Energy Demand of E-Glass”

By compositional modeling, the forming temperature (viscosity) of commercial E-glass melts has been signifi- cantly decreased by decreasing percent SiO2 and increasing percent CaO, and/or by adding a flux such as Li2O. This reduces the energy use and cost, while yielding fibers that meet ASTM and user specifications.
F.T. Wallenberger, R.J. Hicks and A.T. Bierhals
