Process and apparatus for producing non-oxide compounds

Abstract From the Canadian patent

Disclosed are a process for producing non-oxide compounds such as silicon nitride and silicon carbide and a multistage apparatus that is adapted for the process and comprises a raw material drier section, a reactor section including a multiplicity of reaction vessels, and a non-oxidizing gas feeder section. These sections are arranged serially in the vertical direction. The process includes reacting raw materials with one another wile fluidizing or bubbling by a hot non-oxidizing gas (such as argon or nitrogen) in the raw material drier section and reaction vessels.
