摘　　要：以Ｂｉ＿２Ｏ＿３和ＧｅＯ＿２粉为起始物料，经水热反应制得Ｂｉ＿４Ｇｅ＿３Ｏ＿（１２）（ＢＧＯ）微晶粒。晶粒粒度为５～２０μｍ；结晶完好的晶粒呈多面体状。文中对所用前驱物的形式、水热反应的物理－化学条件与产物物相、晶粒形貌关系作了总结。Bi_4Ge_3O_(12) micro-crystallites were hydrothermally synthesized by using bismuth oxide and germa nium dioxide as starting materials.The particle size of the crystallites is in the rang from several to tens of mi cron,and the well-crystallized BGO micro-crystallites have polyhedral shape. In this paper, the relations among the form of precursors, reaction conditions, phase of products and morphology of the crystallites are summarized.
