Properties of Alumina-Platelet-Reinforced 3Y-TZP, Part 1
3Y-TZP containing Al2O3 platelet reinforcements were fabricated
by suspension processing and pressure
less sintering to <95% of theoretical density. The effect of platelet size
on the green and fired microstructures was determined. There was improvement
in mechanical properties using smaller platelets, but loss in fracture strength
using larger platelets. Isaac K. Cherian and W.M. Kriven
High-Alumina Multifunctional Refractory Castables
Versatile multifunctional castables can be installed using ramming, vibrating
and self-flowing methods by changing the water content used during their preparation. A.R. Studart, R.G. Pileggi, V.C. Pandolfelli and J. Gallo
Drying Behavior of Refractory Castables
Knowledge of the drying behavior of castables is an important factor to help
manufacturers of refractories optimize their heating programs, thus minimizing
the time and energy costs involved in the replacement of damaged pieces in the
manufacturing process. M.D.M. Innocentini, C. Ribeiro, J. Yamamoto, A.E. Paiva, V.C. Pandolfelli,
L.R.M. Bittencourt and R.P. Rettore
