At the nanoscale, many materials display properties that differ from their corresponding bulk behavior, which makes them attractive in studies in chemistry and material science. There are many current studies on the properties of oxide nanocrystals, and therefore, an efficient method for their production is essential. One of the most common methods to get oxide nanoparticles is by flame pyrolysis.

This study is an attempt to develop a robust method to produce oxide nanocrystals from liquid-phase precursor solutions in low-pressure premix flames. One of the goals of the study to be able to control the size of the particles produced. It can be possible by varying the flame parameters, the collection site location, and/or the precursor concentration. For this goal the special low pressure flame apparatus was designed and built. In this study, a special reaction chamber was build, and iron oxide nanocrystals were produced used the two methods
