Effects of La2O3 addition on the thermal stability of γ-Al2O3 gels
(Elsevier, 01.01.2004)
The effects of La2O3 additions up to 5 wt.% on the thermal stabilities of sol-gel derived alumina gels were studied. Observations
were made on pore size, total pore area, phase changes at various sintering temperatures ...
