Na. Camargo et M. Murat, MECHANICAL CHARACTERISTICS OF AN ALUMINA CERAMIC PREPARED BY SOL-GEL PROCESS - INFLUENCE OF THE CONDITIONS OF FORMATION OF ALPHA-ALUMINA, Comptes rendus de l'Academie des sciences. Serie II. Mecanique, physique, chimie, astronomie, 319(8), 1994, pp. 893-897
Optimizing the conditions of growth of alpha-alumina during the therma
l transformation of a transition alumina prepared by the sol-gel proce
ss allows us to obtain a hot-pressed alpha-alumina ceramic with low cr
itical defect size, then which presents mechanical characteristics sig
nificantly better than those of alumina ceramics obtained from convent
ional powders.
