Solution combustion synthesis (SCS) is a widely recognized method to synthesize nanoscale materials. In this work, an attempt was made to analytically simulate (using the Semenov method) and evaluate the influence of preheating temperature on flame temperature as well as on physicochemical characteristics of SCS products. Preheating was found to affect combustion temperature only slightly. An increase in preheating temperature led to a decrease in the induction period due to enhanced heating rate and an increase in cooling time as a result of additional exothermic reactions taking place at higher temperatures. Variation in cooling time caused changes in composition and microstructure of product. For the first time, a mathematical model of SCS was suggested.

预热温度对Ni-NiO纳米复合材料溶液燃烧合成的影响：数学模型和实验

固溶燃烧合成（SCS）是一种广泛认可的合成纳米级材料的方法。在这项工作中，尝试进行分析模拟（使用Semenov方法）并评估预热温度对火焰温度以及SCS产品理化特性的影响。发现预热仅轻微影响燃烧温度。预热温度的升高由于升温速率的提高而导致了感应时间的缩短，并且由于在更高的温度下发生了额外的放热反应而导致了冷却时间的增加。冷却时间的变化会导致产品组成和微观结构发生变化。首次提出了SCS的数学模型。
