专利说明书EP-0585544中公开了通过燃烧水解法制备的粉末状硅铝混合氧化物,其具有无定形结构且组成为:65-72.1wt.%Al2O3和27.9-35wt.%SiO2并具有20-200m2/g的BET表面积。
本发明提供一种由燃烧水解法制得的硅铝混合氧化物粉末,其组成为:1-99.999wt.%Al2O3,优选40-80wt.%Al2O3,其余为SiO2,其中该粉末在X-射线衍射图谱中呈现为无定形结构并由共生的初级粒子组成,而在这些初级粒子中存有晶粒,并且这些晶粒具有1-200纳米的尺寸,所述粉末的比表面积为5-300m2/g,优选为50-150m2/g。
本发明也提供一种制备由本发明的燃烧水解法制得的硅铝氧化物粉末的方法,其中将卤化硅和卤化铝以指定的相互比率气化并在一混合设备中通过载体气而与空气、氧气和氢气均匀混合,该混合物在一已知结构的燃烧器中进行燃烧,当从气相中分离出固体以后,在另一处理步骤中于高温下利用湿空气将可能粘附在所述产物上的任何微量的卤化物除去。
现已发现,将制成悬浮分散体的本发明的硅铝混合氧化物作为抛光剂具有极佳的性能。
这些悬浮分散体特别是可在电子工业(CMP)中用于抛光。
本发明的硅铝混合氧化物也可在电子工业中用作填料、载体材料、催化活性物质、陶瓷原材料,用作聚合物的填料,用作制备玻璃或玻璃涂料或玻璃纤维的原材料,在化妆品工业中用作隔离助剂,在硅氧烷和橡胶工业中用作吸收材料、添加剂,用于调节液体体系的流变性,用于防热稳定化,在牙科工业中用作隔热材料、流动控制剂,在制药工业、涂料工业、聚乙烯薄膜应用、荧光管中用作助剂,用于制备过滤器陶瓷或过滤器原材料,在墨水和电池隔板中以粉末形式用作调色剂、除锈剂,用作聚乙烯和聚醋酸乙烯酯薄膜涂层的添加剂。
实施例
相应于在EP-0585544的实施例1中介绍的已知燃烧器装置,指定将下述用量用于制备混合氧化物。实施例1
将从燃烧器或从反应中得到的1.6Nm3/h氢气与5Nm3/h空气和1.70kg/h已气化的SiCl4混合到一起。此外,将2.5kg/h气态AlCl3(其已在约300℃下气化)加入至温度约为200℃的所述混合物中。在一燃烧管中燃烧该混合物,另外同时将12Nm3/h空气加入至该燃烧管。
在所述材料穿过燃烧管后,将所得的粉末在一过滤器或旋流器中从含有盐酸的气体中分离出来,且所粘附的微量盐酸通过在高温下处理而从所得的混合氧化物中分离出来。
所述混合氧化物的分析数据如下:
BET比表面积为56m2/g,4%的悬浮分散体的PH值为4.52,堆积密度49g/l,填实密度为59g/l。所述粉末的组成为:63.6wt.%Al2O3,36.3wt.%SiO2。实施例2
将从燃烧器或从反应中得到的1.2Nm3/h氢气与6Nm3/h空气和1.70kg/h已气化的SiCl4混合在一起。此外,将2.5kg/h气态AlCl3(其已在约300℃下气化)加入至温度约为200℃的所述混合物中。在一燃烧管中燃烧该混合物,另外同时将12Nm3/h空气加入至该燃烧管。
当所述材料穿过燃烧管后,将所得的粉末在一过滤器或旋流器中从含有盐酸的气体中分离出来,且所粘附的微量盐酸通过在高温下处理而从所得的混合氧化物中分离出来。
所述混合氧化物的分析数据如下:
BET比表面积为99m2/g,4%的悬浮分散体的PH值为3.9,堆积密度39g/l,填实密度为48g/l。所述粉末的组成为:64.4wt.%Al2O3,35.52wt.%SiO2。粉末的其它特征
所述粉末具有下述特征:这些粉末的X-衍射图谱(实施例1的图1)表明,在所述粉末中实际上没有晶体相。
但同时,高分辨率电子显微镜表明,所述粉末的初级粒子包含部分晶体区域,这可能决定了用这些混合氧化物制备的分散体具有好的抛光性能(图2)。
