摘要: 分别采用硝酸盐自蔓延燃烧法和醋酸盐/硝酸盐自蔓延燃烧法低温合成了La2CuO4前驱物粉体，研究了在不同条件下制备的前驱物粉体的晶化行为。在硝酸盐自蔓延燃烧法合成前驱物粉体时，燃烧反应十分剧烈，在前驱物粉体中发现有Cu单质存在，Cu单质的存在不利于在低温合成单一相La2CuO4粉体。在硝酸盐自蔓延燃烧法基础上，以醋酸盐部分取代硝酸盐，大幅度降低了自蔓延燃烧温度，可以通过调整尿素的用量来改变氧化剂的总氧化价O与还原剂的总还原价F之比，使自蔓延燃烧温度连续可调。用醋酸盐/硝酸盐自蔓延燃烧法合成的前驱物粉体在较低温度焙烧处理，得到了单一相La2CuO4粉体。自蔓延燃烧温度对前驱物的组成和焙烧产物的组成和显微形貌有显著影响。自蔓延燃烧温度连续可调为得到具有可控制显微形貌的目标产物提供了可能。
