My professor asked me to make my own spray pyrolysis nozzle for making a transparent conducting oxide glass which i'll be using for my dye sensitized project. is it possible to make our own spray pyrolysis nozzle?
this link contains a paper that can help you building your spray set up and run your process. It is really in the focus of your needs:http://iosrjournals.org/iosr-jap/papers/Vol7-issue2/Version-3/F07233945.pdf
You can easily make a nozzle with two glass droppers. Please refer the attached file for the method. When you heat the droppers, better use a gas burner and make sure its not over heated, or else it will melt. And the next thing to take care is when you break the excess tube portion. Try to use a glass cutter before breaking. Cut a little around the tube and then break.
One can make but you should think whether your workshop personnel can do that to the accuracy that one attains in a nozzle made by industry using computer controlled machines.
