“…Yu and Liao developed a model describing the evaporation of solution droplets before the formation of a solid crust [42]. The transfer of mass, momentum, temperature outside and around the droplet as well as effects of precursor precipitation were taken into account.…”

Spray pyrolysis has been applied to deposit a wide variety of thin films. These films were used in various devices such as solar cells, sensors, and solid oxide fuel cells. It is observed that often the properties of deposited thin films depend on the preparation conditions. An extensive review of the effects of spray parameters on film quality is given to demonstrate the importance of the process of optimization. The substrate surface temperature is the most critical parameter as it influences film roughness, cracking, crystallinity, etc. Processes involved in the spray pyrolysis technique are discussed in this review as well.

“…On the other hand, if the drops are sprayed against the substrate with sufficiently high strength, spread lightly, maintain an evaporation rate equivalent to the solute precipitation rate, the solute nucleates and precipitates homogeneously, creating a dense and continuous film (Yu & Liao, 1998).…”

“…Its detailed procedure was explained elsewhere [6][7][8]. System of the ordinary differential equations resulting from material and energy balances of a droplet, and Fick's second law of diffusion within the droplet was solved simultaneously by an ordinary differential equation solver, IVPAG in IMSL package.…”

“…Their criterion was whether at the moment the concentration in the droplet center reached the saturation or not. Their approach was extended by Yu et al [7] and Lenggoro et al [8] with little modification. On the other hand, Jain et al [9] emphasized the importance of salt(A)-to-product(B) transformation rather than salt precipitation, focusing the effect of density increase or volume contraction during the transformation.…”

Nickel oxide particles were prepared by spray pyrolysis of aqueous solution of NiCl 2 ·6H 2 O. In the reactor the salt droplets were first converted to hollow particles by drying and then they were collapsed by oxidation to reduce their size. Each oxide particle was composed of many small nuclei with voids among them due to extremely low rate of sintering. The particle size decreased with the temperature as the sintering and crystallization proceeded. The size as well as the crystallinity of the particles increased with the initial salt concentration. When the salt droplets were preliminarily dried in diffusion dryer before entering the reactor, the collapse of the particles was considerably reduced, resulting in lower hollowness and higher sphericity. Numerical simulation on the drying of the droplets provided insight on the initial stage of spray pyrolysis.
