Ultrafine alumina (Al2O3) has a series
of excellent features such as the very high chemical stability, thermal
stability, high hardness and corrosion resistance etc. It has been widely used
at present. Therefore, the research of ultrafine aluminum oxide powder and the
choice of the best optimization scheme have important significance for the
manufacturing of ultrafine aluminum oxide powder of the high yield, good loose,
small particle size and uniform distribution. Precipitation is applied in this
study, and manufacture ultrafine alumina powder with aluminium chloride and the
precipitating agent preparation as raw material. Through researching the
influence of the precipitant on alumina powder, we find ammonium bicarbonate can
be taken as the best precipitant. After the XRD and laser particle size
measurement of calcination samples, test results show that; aluminum oxide
powder manufactured with aluminium chloride and ammonium bicarbonate as raw
material by precipitation method has the advantages of the good dispersivity,
the smaller particle size and high purity. The technology has the characters of
simple process, convenient operation and low cost. Therefore, it is easy to
realize industrial production.

Superfine alumina (Al2O3) has higher chemical stability, thermal stability, high hardness and corrosion resistance and a series of excellent properties, has been widely used now. Therefore, research on ultrafine alumina powder preparation, selection of optimal scheme optimum, preparation of high yield of loose, good, has the important meaning of ultrafine alumina powder with small particle size and uniform distribution. This study used precipitation method, with aluminum chloride and the precipitation agent for the preparation of ultrafine alumina powder raw material, through the research of the precipitation agent for alumina powder, ammonium bicarbonate can be found as the best precipitant. Determination of XRD and laser granularity on samples after sintering, test results show that the precipitation method; with aluminum chloride and ammonium bicarbonate as raw materials preparation of ultrafine alumina powders with good dispersion, particle size and high purity advantages. This technology has the advantages of simple process, convenient operation, low production cost, easy realization of industrial production.

Ultrafine aluminum oxide (Al2O3) has a high degree of thermal stability, chemical stability, high hardness and excellent corrosion resistance and a series of characters, has now been widely used. Therefore, research on preparation of Superfine alumina powder, choosing the best optimization, on the preparation of high yield, loose is good, small and uniform distribution of particle size of ultrafine alumina powder is of great significance. Study on precipitation, with aluminum chloride and precipitating agent for preparation of Superfine alumina powder, by studying the effects of precipitation agent on alumina powder and found that precipitation agent Ammonium bicarbonate as you can for the best. XRD the calcined samples and laser particle size measuring, test results show that through precipitation with aluminum chloride and Ammonium bicarbonate as raw material preparation are dispersibility of ultrafine alumina powders with benefits of better, smaller size and higher purity. This technology with process simple, convenient operation, generating low cost, easy to implement in industrial production.

Ultrafine Alumina (Al2O3) having a high chemical stability, thermal stability, high hardness and corrosion resistance and a series of excellent characteristics, has been widely used. Therefore, the preparation of ultrafine alumina powder, choose the best optimization program, on the preparation of the production rate, loose, good, small size and uniform distribution of ultrafine alumina powder has an important significance. In this study, precipitation, aluminum chloride was prepared from each precipitant ultrafine alumina powder, precipitated by studying the influence of agents on the alumina powder, ammonium bicarbonate can find the best precipitant. After the samples were calcined XRD and laser particle size measurement, the test results show; precipitation method using aluminum chloride and ammonium bicarbonate as raw material to obtain ultrafine alumina powder has better dispersion, smaller particle size and high purity advantages. The technology has a simple process, easy to operate, generate low cost, easy to implement industrial production.
