Two Zone Rotary Tube Furnace for Powder CVD Coating and Core Shell Material Synthesis 1100C

Product Overview

This high-performance two-zone rotary tube furnace is a specialized thermal processing system engineered for the precise synthesis and treatment of powder materials. Designed to operate at temperatures up to 1100°C, the equipment integrates a rotating reactor tube with a dual-heating zone configuration, enabling researchers and industrial engineers to perform complex Chemical Vapor Deposition (CVD) and calcination processes. The system is particularly optimized for high-energy battery material development, where the uniform coating of powders and the creation of core-shell structures are critical for electrochemical performance.

In industrial R&D and pilot-scale production, the primary value of this unit lies in its ability to maintain dynamic thermal equilibrium. By utilizing a rotating 5-inch quartz tube equipped with integrated mixing blades, the equipment ensures that every particle within the processing batch is exposed to the same thermal and atmospheric conditions. This eliminates the common issues of dead zones and uneven heating associated with static furnace designs, making it an essential tool for the synthesis of silicon-nanolayer-embedded graphite, inorganic material calcination, and advanced catalyst preparation.

Built with a focus on durability and process repeatability, this furnace system features a robust mechanical design coupled with advanced atmosphere control. The integration of high-precision magnetic fluid seals allows for reliable operation under controlled atmospheres and vacuum conditions, providing the stability required for sensitive material science applications. Procurement teams and laboratory managers can rely on this equipment for consistent, high-yield results in demanding material research environments, from lithium-ion battery optimization to the production of high-purity ceramic powders.

Key Features

• Dual-Zone Precision Heating: The system features two independently controlled heating zones with a combined heating length of 280 mm, allowing for a precise temperature gradient or extended isothermal zones up to 1100°C.
• Dynamic Rotary Processing: Equipped with a variable speed rotary drive (0-10 rpm), the unit ensures continuous tumbling of powder materials, maximizing surface area exposure to the reaction atmosphere and heat source.
• Integrated Mixing Blades: The 5-inch fused quartz tube includes four internal mixing blades that facilitate the mechanical lifting and folding of powders, ensuring total homogeneity during the CVD or calcining process.
• Advanced Magnetic Fluid Sealing: To maintain high-purity atmospheres and vacuum integrity, the system utilizes a pair of rotary inline magnetic fluid seals, ensuring leak rates of less than 5 mtorr per minute.
• Standalone PID Control Tower: A dedicated control unit houses two 30-segment programmable PID controllers, providing ±1°C temperature accuracy and the ability to manage complex thermal profiles remotely from the furnace body.
• Versatile Atmosphere Management: The system is designed for atmosphere-controlled processing, featuring 1/4" tube fittings for gas inlet and outlet, making it compatible with various precursor gases and inert environments.
• High-Volume Throughput: With a tumbling volume of 3000 ml and an effective powder processing volume of up to 750 ml, this equipment bridges the gap between laboratory-scale experimentation and pilot-scale production.
