description A method of making spherical gettering particles for an environmental barrier coating according to an exemplary embodiment of this disclosure, among other possible things includes spraying liquid preceramic polymer into a chamber via a nozzle to form liquid droplets or a stream of liquid droplets, curing the liquid droplets to form spherical particles in the chamber, and converting the spherical particles to spherical ceramic gettering particles in either a fluidized bed or by directing the stream of cured particles through a torch. An environmental barrier coating and an article are also disclosed.
