ECS-N Fluidized Bed Chemical Vapor Deposition (FBCVD) Furnace (Max. 1200℃, Triple-Zones) with Automatic Feeder and Mist Generator for Powder Coating, ENFBCVDFAFMG

A Fluidized Bed Chemical Vapor Deposition (FBCVD) Furnace with an Automatic Feeder and Mist Generator is a sophisticated, integrated platform designed for the core-shell coating of powders. In this setup, the "fluidization" ensures every particle is suspended in a gas stream, while the "mist generator" introduces liquid precursors as an aerosol, allowing for the deposition of high-quality oxides, polymers, or metals at atmospheric or low pressure.

This "3-in-1" system (Fluidization + Automatic Feeding + Mist Generation) eliminates the manual handling of powders and precursors, ensuring high repeatability for large R&D projects. (1) Automatic Solid Feeder: Typically a volumetric screw feeder or a vibratory feeder. It precisely meters the raw cathode/anode powder into the furnace at rates like 1–100 mL/min. (2) Ultrasonic Mist Generator: Uses a high-frequency transducer (1.7 MHz to 2.4 MHz) to atomize liquid solutions into a sub-micron mist. This mist is then carried by an inert gas (Ar) into the fluidized bed. (3) Vertical Fluidized Bed Furnace: A vertical tube furnace where the powder is suspended in the mist/gas mixture. The "fluid" state allows the mist to surround each particle uniformly.  Automatic Receiver/Cyclone: A collection system at the top of the furnace that uses a cyclone separator to capture the coated powder while letting exhaust gases escape.
