高质量的陶瓷粉末可以由均匀沉淀。这种方法允许控制纯度、颗粒大小、形状、分布和同质性,知道这些因素发挥非常重要的作用,完成了陶瓷材料的属性。氧化铝纳米粒子可以从外加剂的解决方案获得的硫酸铝和亚硫酸氢铵。均匀沉淀在pH值4.2,当解决方案的混合加热分解和沸腾温度。Nano,球面与尺寸分布窄,硫酸铝和软凝聚,基本(BAS)很容易产生。粉末被加热在950 oC硫酸分解然后煅烧α-alumina 1250 oC变换。否则,治疗BAS铵水溶液,可以转化为纳米级的纤维pseudoboehmite沉淀,可转化为α-alumina煅烧。另一方面,准备莫来石前驱,最初的硅纳米粉体(200年气相二氧化硅,德固赛)是在水中分散和混合解决方案的硫酸铝和亚硫酸氢铵。掺合料在加热分解和沸点,在沉淀二氧化硅的BAS是覆盖着。这个前体转化为莫来石加热在1250°C。 The other application example of this homogeneous precipitation is used to prepare in the fabrication of basic chromium sulfate. Starting from the admixture of solutions of chromium sulfate and ammonium bisulfite, the basic chromium sulfate can be precipitated. But in the last case it is not easy for all chromium precipitate since chromium forms a water soluble complex with ammonia. Even though, almost every chromium can be precipitated. In this presentation, a simple useful technique of homogeneous precipitation for preparing the basic sulfate salts of metals starting from the admixture of metal ion-sulfate-sulfite-ammonia aqueous system is discussed.

Satoshi杉田有自己的专长,陶瓷粉处理。准备他的均匀沉淀法前体提供机会获得纳米级陶瓷粉末的基本金属盐,把容易软凝聚陶瓷粉末,即纳米纤维γ-alumina、球形α-alumina,球形和莫来石纤维,等。用这个均匀降水、亚硫酸氢铵用作沉淀剂、反应条件的控制是非常简单的。这种技术已经准备不同类型的陶瓷粉末的可能性。
