Four ceramic powders were produced using the glycine–nitrate process: lanthanum‐doped barium cobaltite, ceria, magnesia, and strontium‐doped lanthanum chromite (LSC). Glycine‐to‐nitrate ratios from 0.25 to 1 were investigated. During the combustion synthesis process, careful collection of process off‐gas was followed by detailed gas analyses to determine product gas composition. All of the synthesis processes produced pure phase ceramic powders, but also produced criteria pollutant emissions levels that were significant enough (up to 4500 ppm of NO x and 9000 ppm of carbon monoxide) to warrant consideration. Equilibrium and chemical kinetic computations are used to determine the implications of the current findings.
