鋁酸鑭超細(xì)粉體的制備方法 The preparation techniques of lant:綜述了目前常用的制備鋁酸鑭粉體的各種方法之工藝過程、特點(diǎn)及其產(chǎn)物的性能特征.分析指出:純度和粒度是粉體重要的兩個(gè)性能指標(biāo);降低合成溫度、簡(jiǎn)化工藝過程是今后制備技術(shù)發(fā)展的趨勢(shì);金屬醇鹽可能成為獲得高純度產(chǎn)物有應(yīng)用前景的前驅(qū)物,醇鹽水解法有望成為的制備工藝路線. Processes and characteristics of various techniques preparing lanthanum aluminate powders, and their product properties are reviewed briefly. Its purity and particle size distribution are two most important indexes o。
