    ZYLAB 1200°C Dual-Zone Vertical Fluidized Bed CVD (FBCVD) Furnace Introduction: The ZYLAB Vertical Fluidized Bed CVD (FBCVD) Furnace with Automatic Feeding and Discharging System is designed for continuous chemical vapor deposition processing of powder materials. The system adopts a vertical fluidized bed structure with automatic feeding and discharge, enabling stable gas–solid reactions and uniform coating deposition. With a maximum sulfurization temperature of 1200°C, dual temperature zones, and an advanced fluidization chamber design, the furnace allows powders to remain suspended in the reaction zone where they react with heated gases to form new materials or coatings. This technology is widely used in lithium battery materials, nuclear fuel particle coating, catalytic materials, and advanced thermal management materials. Working Principle of Vertical Fluidized Bed CVD Furnace: During operation, the powder sample is placed in the upper sulfurization chamber with controlled temperature. The reaction gas is heated at the bottom of the system and then enters the sulfurization chamber through a fluidized bed distributor plate with pore size of 10–16 μm. The upward gas flow suspends the powder particles within the heating zone of the furnace, forming a stable fluidized state. The suspended particles continuously react with the reactive gas, enabling uniform chemical vapor deposition or sulfurization reactions. The furnace tube is made of high-purity quartz, and both ends are sealed with stainless steel flange assemblies, ensuring excellent vacuum performance and reliable operation under controlled atmospheres. Key Applications： Lithium Battery Materials The system enables large-scale preparation of silicon–carbon anode materials, with continuous feeding and discharging capabilities and carbon coating thickness deviation controlled within ±5%. It can also be used for oxide or low-temperature carbon coating of ternary and lithium-rich cathode materials, improving electrochemical stability and cycle life. Nuclear Fuel Coating The reactor supports multi-layer coating of TRISO fuel particles, ensuring the dense formation of SiC and PyC protective layers, which effectively isolate fission products under high-temperature conditions. Thermal Management Materials Graphene can be grown on alumina particle surfaces to produce high thermal conductivity interface materials used in electronic thermal management systems. Catalysts and Functional Materials The fluidized bed structure allows uniform loading of metal active components, improving catalytic reaction efficiency. Sodium-ion Battery Materials and Environmental Adsorbents The equipment is also suitable for surface modification of sodium-ion battery materials and functionalization of environmental adsorption materials, making it an important tool for large-scale production of high-performance functional powders.
