摘要
Al(OH)_3胶体溶液在微波辐照下.能够生成均匀的超细Al2O3晶体粉末(约0.07μm);在有表面活性剂或分散剂时,得到的是非晶态的胶态粉末.长时间的微波辐照,对粉末质量没有影响.
Al(OH)3 colloidal solution can be changed to Crystalline Al2O3 superfine powder(about 0.07um) undermicrowave mediation. If the solution has suffice above agent or dispersing agent, the Al2O3, powder isnon-crystalline. The long time of microwave iradiation has no affection on quality of Al2O3.
