Biswas, Taniya (2009) Effect of Washing on Strength and Weibull Modulus of Alumina. BTech thesis.
Reactive alumina from NALCO was washed and aged in DI water for 3, 6 and 10 days. The as received as well as the aged powders were uniaxially compacted and sintered at 1500⁰C for different holding periods (2, 4, and 6 hours). The density and biaxial flexure strength carried out on different sintered samples show a strong effect of washing on the above property. Weibull modulus was found to be higher for longer ageing periods indicating a possibility of particle size redistribution during washing and ageing. The highest Weibull modulus of 6.57 was obtained.
