Abstract
The feasibility of electrostatic precipitation at high temperature was demonstrated for the separation of the ultra-fine particles synthesized by thermally activated CVD ( Chemical Vapor deposition) from the reaction gas stream. Silicon nitride particles were prepared from a SiCl4/NH3 system at 1200°C. This process produces the NH4Cl by-product which is a solid particle at normal temperature. Using the high temperature electrostatic precipitation method, it is expected that the Si3N4 product can be collected without the by-product (NH4Cl) from reaction gas because the sublimation temperature of NH4Cl is about 340°C. The new electrode system for corona discharge was developed because stable corona discharge was not obtained in the reaction gas atmosphere at high temperatures. The X-ray diffraction shows that the particles collected on the electrode at 500°C contains no NH4Cl particle.
