| Abstract |
| Isothermal sintering of calcium monoaluminate and dialuminate
powders (-45 1-1m) has been carried out to study their
densification behaviour in the temperature range 1380° to 1450°C.
The soaking periods varied from 10 to 240 min. The data were
analyzed using Arrhenius equation and the equation D = K log t
+ C where Dis the bulk density and tis the sintering time, K and
C are constants. It was found that CaAI20 4 requires an activation
energy of 120 KJ.mol-1 and that CaAI40 7 requires 165 kJ.mol-1• |
