Pyrosol® process

Such polarized EXAFS measurements were carried out to study the structure of undoped and indium doped ZnO thin films prepared by the pyrosol process [11, 20]. Such films are promising materials as gas sensors, ultrasonic oscillators, piezoelectric transducers, and transparent electrodes in solar cells.

In this book, we briefly examine the different types of reactions and methods employed in the synthesis of inorganic solid materials. Besides the traditional ceramic procedures, we discuss precursor methods, combustion method, topochemical reactions, intercalation reactions, ion-exchange reactions, alkali-flux method, sol-gel method, mechanochemical synthesis, microwave synthesis, electrochemical methods, pyrosol process, arc and skull methods and high-pressure methods. Hydrothermal and solvothermal syntheses are discussed separately and also in sections dealing with specific materials. Superconducting cuprates and intergrowth structures are discussed in separate sections. Synthesis of nanomaterials is dealt with in some detail. Synthetic methods for metal borides, carbides, nitrides, fluorides, sili-cides, phosphides and chalcogenides are also outlined. 

In addition to these sputtering techniques, a few workers have used other techniques, for example, glow discharge [202], and the Pyrosol process [203]. But these processes have not been widely used.
