Fluidized bed chemical vapor deposition (FBCVD) is a process technology use to coat powders or particles. The fluidized bed reactor (FBR) is designed to allow for injecting a fluidizing gas with the appropriate vapor or gas CVD precursor.

The preparation of coated fuel particles using fluidized bed-chemical vapor deposition (FB-CVD) is one of the key processes in the production of fuel elements for high-temperature gas-cooled reactors.

Abstract: Fluidized bed-chemical vapor deposition (FB-CVD) is widely used in industrial production owing to the combined advantages of both fluidized bed and chemical vapor deposition. Providing good heat and mass transfer, it can …

2007年9月25日 · The Computational Fluid Dynamics code MFIX was used for transient simulations of silicon Fluidized Bed Chemical Vapor Deposition (FBCVD) from silane (SiH 4) on coarse alumina powders. FBCVD experiments were first performed to obtain a reference database for modelling.

Fluidized bed-chemical vapor deposition (FB-CVD) process is a common method in particle surface modification and particle coating layers preparation. The typical application is the production of the tristructural-isotropic (TRISO) type coated fuel particle, as shown in Fig.1, which has been commonly used in the current HTGR in

2012年12月1日 · Fluidized bed reactors hold the potential to become the dominating CVD reactor for production of solar grade silicon. Large players in today's market like Renewable Energy Corporation (REC) and MEMC are producing increasing amounts of their material through FBR instead of Siemens reactors.

Fluidized bed chemical vapor deposition (FBCVD) is one of the most efficient techniques to functionalize, to deposit on, or to coat each individual particle of a powder from gaseous species. FBCVD combines two processes. One is the deposition itself, the other aims in suspending the particles in the deposition zone, most often by flowing

Fluidized bed reactors, abbreviated throughout the paper as FBR’s, are widely used in Chemical Engineering and combustion technology for processes which need a very good heat and mass transfer between particles and a fluid, namely a gas phase or a liquid.

A new concept of fluidized bed will be shown which can be used for various gas-to-solids reactions (e.g. chemical vapour deposition (CVD) reactions) with high throughput like the production of new materials.

2007年9月10日 · Among the different techniques used for their synthesis, catalytic (C)CVD in fluidized-bed reactors appears one of the most promising. In this article we present the current state of this new technology and we aim to highlight its great flexibility through examples which depict the selective preparation of different kinds of carbon ...
