Morphology of Single-Component Particles Produced by Spray Pyrolysis

摘要: ABSTRACT This work is a review of the experimental results from literature for single-component metal and simple metal-oxide particles. Criteria correlating particle morphology, i.e., whether particles are solid or hollow, with process parameters material properties during spray pyrolysis presented compared data available in literature. The materials were classified into two categories which precursor: (1) melts (2) does not melt before chemical reaction takes place, separate criteria used each category based on Jayanthi et al. (1993) J. Aerosol Sci. 19:478. In systems where precursor occurs, e.g., decomposition nitrates Mg, Al, Fe, Zn, Pb, Ni, Co, Pd, Mn, Cu, Sr, Ag, morphology determined primarily by densities formula weights reactant product compounds unless high temperature densification puffing up due to gases evolved ...
