The invention provides a reactor for the manufacture of silicon by chemical vapor deposition (CVD), the reactor comprises a reactor body that can rotate around an axis with the help of a rotation device operatively arranged to the reactor, at least one sidewall that surrounds the reactor body, at least one inlet for reaction gas, at least one outlet for residual gas and at least one heat appliance operatively arranged to the reactor. The reactor is characterized in that during operation for the manufacture of silicon by CVD, the reactor comprises a layer of particles on the inside of at least, one sidewall.

Reactor and method for production of silicon by chemical vapor deposition

Reactor for producing silicon by chemical vapor deposition, the reactor comprising a reactor body that forms a container, at least one inlet for a silicon-bearing gas, at least one outlet, and at least one heating device as a part of or operatively arranged to the reactor, distinctive in that at least one main part of the reactor, which part is exposed for silicon-bearing gas and which part is heated for deposition of silicon on said part, is produced from silicon. Method for operation of the reactor.
