“…It is used as a catalyst and catalyst substrate in automotive and petroleum industries, structural composites for spacecraft, and abrasive and thermal wear coatings [9]. Recent studies have shown that γ-alumina is thermo dynamically stable relative to α-alumina when a critical surface area is achieved [10], and that nano γ-alumina powder can promote the sintering behaviour of alumina and silicon carbide fibbers [11], and also that the use of single phase of γ-alumina powders makes the densification temperature shift to lower temperature as compared with the sample consisting of γ-and χ-alumina [12].…”

“…Particulamente, a γ-alumina que apresenta grande área de superfície, estrutura porosa e acidez superficial, é um importante suporte catalítico. (Ma, Zhu, 2009, Wang et al, 2009). …”

“…A alumina é um material estrutural importante, com a ampla aplicação técnica e de enorme importância no campo da catálise heterogênea (Ma e Zhu, 2009;Wang et al, 2009). As aluminas de transição atuam como catalisadores ou como suportes catalíticos para outros metais em inúmeras reações catalíticas.…”
