ABSTRACT:
A method is disclosed for producing solid materials in form of microspheres or spherules for a number of applications, such as nuclear fuel, catalyst, fluid beds for fluidization and other like applications. An inert gas shield is provided to surround the droplets of liquid from which the microspheres shall be originated so as to prevent a premature reaction of such droplets with the reactive gas. Provision is made for renewing the braking foam placed over the liquid reactive bath and the reactive gas is supplied in the form of a blade-like stream so as to improve the contact time and intensity between the droplets and the reactive gas.
