In a typical flame synthesis process, a precursor material, often in the form of a liquid or gas, is introduced into a flame. The high temperature of the flame causes the precursor to undergo thermal decomposition, resulting in the formation of vapor-phase species. These species then nucleate and grow into nanoparticles. The size, shape, and properties of the nanoparticles can be controlled by adjusting the flame parameters, such as temperature, flow rates, and precursor concentration.
