超细氧化铝（Al2O3）具有很高的化学稳定性、热稳定性、高硬度及耐腐蚀性等一系列优良特性，目前已得到广泛应用。因此，研究超细氧化铝粉末的制备，选择最佳的优化方案，对制备出产率高，疏松性好，粒径小且分布均匀的超细氧化铝粉末有着重要意义。本研究采用沉淀法，以氯化铝和各沉淀剂为原料制备超细氧化铝粉体，通过研究各沉淀剂对氧化铝粉末的影响，发现碳酸氢铵可以为最佳沉淀剂。对煅烧后样品进行XRD和激光粒度测定，检测结果表明；采用沉淀法以氯化铝和碳酸氢铵为原料制备得到超细氧化铝粉末具有分散性较好、粒径较小以及纯度较高的优点。该工艺技术具有流程简单，操作方便，生成成本低，易于实现工业生产。 里面的专有名词要用知网翻译助手里的有的，急用   |

ultrafine Al2O3 powders are of high chemical stablility, thermal stablity, highhardness and good anti-corrosion properties and have been widely applied. optimized approach was approached to investigate the ultrafine Al2O3 powder. therefore, it is meaningful to prepare ultrafine Al2O3 powders of high yielding, good porosity,small size with good distributions. In our work, AlCl3 and other precipitants were used as raw materials to prepare ultrafine Al2O3 powde by precipitation method. effects of all precipitants on the quality of Al2O3 powders were investigated. it was fond that 碳酸氢铵 to be the best candidate of precipitate. XRD and laser particle size examinaztion were used on calcined samples. the results indicate that the ultrafine Al2O3 powders obtained by using AlCl3 and 碳酸氢铵 as raw materials were of good dipersity, small size and high purity. such processing are significant by saimple procedure, easy operation, low cost and easy realization of industrila productions. |
