alpha phase meaning in Chinese

α震相

Ajs20 , the precursor contained 20wt % alunina sol seeding , was calcined at around 1000 to get free - aggregation nano - sized a - alaos powders with a median particle size of 70nm . and , calcining ajs2 , the precursor contained 2wt % alumina sol seeding , at hoo ' c , we get a - alaos nano - sized powders with a particle size of loonm and good dispersion by tem . this paper also gives the proper mechanisms of these factors " influences on the transformation to alpha phase
研究结果显示，含有20wt胶体籽晶的前驱体ajs20在1000左右煅烧就可获得平均粒径为70nm 、无团聚的纳米- al _ 2o _ 3粉体；而含有2wt胶体籽晶的前驱体ajs2在1100即可获得粒径在100nm左右、几乎单颗粒分散、有少量“树枝状”微结构的纳米- al _ 2o _ 3粉体。
