It was discovered that MgO could restrain the phase transformation of metastable alumina to stable α-Al2O3 and change the crystallization habit of α-Al2O3.
研究发现,MgO可以抑制亚稳态氧化铝向稳定态α-Al2O3的物相转变,同时还可以改变α-Al2O3的结晶习性,在没有添加剂的作用下,生成的α-Al2O3是蠕虫状空间网状结晶,在MgO作用下,α-Al2O3晶粒细小,晶粒之间的结合不规则,其原因在于MgO是一种高挥发物质,与Al2O3反应,与在α-Al2O3的晶界处形成MgAl2O4,阻止α-Al2O3晶粒生长。

补充资料：相转化
分子式：
CAS号：
性质：相转化是指铸膜液的溶剂体系为连续相的一个高分子溶液，转变为高分子是连续相的一个溶胀的三维大分子网络式凝胶的过程。这种凝胶就构成了相转化膜。例如在铸膜液的制膜过程中，由高分子溶液转化成固相的高分子分离膜。聚砜铸膜液是以N,N-二甲基乙酰胺为连续相的高分子溶液，在平板玻璃上刮制成均匀的液膜后，立即浸入水中，二甲基乙酰胺溶入水里，这就使以溶剂为连续相的高分子溶液，转变成以聚砜为连续相的三维大分子网络式凝胶，形成了聚砜分离膜，这一转变过程，称相转化。
