Flame assisted spray pyrolysis equipment is fitted with accessories required for controlling the flame during the process. The solution is sprayed using a positive displacement pump and compressed air through a mixing chamber and nozzle. The substrate is placed on a hot plate, the temperature of which can be set at the desired level through a dedicated controller. The hot plate is mounted on a motorized XY platform to move the substrates during the coating process in the required sequence so that uniform coating is achieved.
Flow rate of the solution and motion sequence of the substrate are controlled through a personal computer. The flame is initiated and set at the required intensity level manually using the control accessories fitted with the equipment. As the solution is sprayed with the help of compressed air, the equipment can be used for spray pyrolysis without flame as well. The combination of pyrolysis thin films with and without flame can also be produced on the same substrates in successive operations.
In flame assisted spray pyrolysis, this spray is heated by a flame produced by an oxy-LPG gas mixture, before being deposited onto the substrate.n this technique, the solution is sprayed onto a heated substrate through an LPG flame.The chemical reactants are selected such that products other than the desired compound are volatile at the temperature of deposition. The process is generally useful for the deposition of oxides onto metal and ceramic substrates and particularly suitable for the deposition of Al2O3, ZnO and metastable solid solutions of ZnO-MgO and ZrO2-Y2O3 on amorphous silica and Nickel based super alloys.
