Introduction:
The KJ-T1200-S80 is a high-temperature tube furnace with a dual-furnace structure, consisting of a 200mm heating zone and a 150mm insulation zone. The two zones can be independently controlled, enabling temperature gradient or segmented heat treatment within the same furnace tube. The equipment has a maximum operating temperature of 1200℃ and a continuous operating temperature of 1100℃, suitable for sintering, annealing, CVD, and pyrolysis experiments on various materials.
The furnace body employs a double-layer shell and air-cooling system, ensuring the shell temperature is ≤50℃ for safe and comfortable operation. The furnace chamber is constructed from high-purity alumina polycrystalline fiber through vacuum adsorption (Japanese technology), providing excellent insulation and a uniform temperature field. The furnace tube is equipped with a standard high-purity quartz tube (customizable size), with stainless steel sealing flanges at both ends (one end with a standard flange, the other with a hinged flange) for easy sample loading and unloading, and supports vacuum or protective atmospheres. The heating element is a molybdenum alloy resistance wire, paired with an N-type thermocouple and a 30-segment programmable PID temperature control system, providing independent temperature control for both zones with reliable accuracy.
Application Areas
The dual-temperature zone design makes it particularly suitable for processes requiring temperature differences or segmented control, specifically including:
1. Chemical Vapor Deposition (CVD) and Two-Dimensional Material Growth
Separate temperature control for the precursor evaporation zone and the deposition zone: For example, in the growth of graphene, molybdenum disulfide (MoS₂), boron nitride, etc., the upstream low-temperature (200-400℃) precursor volatilizes, while the downstream high-temperature (600-1000℃) deposition reaction takes place.
2. Gradient Heat Treatment and Material Modification
Temperature gradient sintering: Studying the effects of different temperatures on material phase transformation and grain growth within the same furnace tube.
Gradient reduction/oxidation: Differentiated treatment of long samples with reduction at one end and oxidation at the other.
3. Powder Metallurgy and Ceramic Preparation
Segmented debinding and sintering: Integrating the organic debinding zone (300-500℃) and the ceramic densification zone (1000-1200℃) into the same furnace tube.
4. Pre-sintering and final sintering of cemented carbide and metal powders.
5. Synthesis of New Energy Materials
Lithium-ion battery cathode and anode materials: solid-state reactions of materials such as lithium iron phosphate and ternary materials; carbon coating of silicon-carbon anodes (low-temperature carbonization + high-temperature graphitization segmentation).
Calcination of fuel cell electrolyte powders.
6. Catalysis and Chemical Engineering
Evaluation of fixed-bed catalysts: dual-temperature zones allow for separate control of the preheating section (gasification of feedstock) and the reaction section (catalytic conversion), simulating industrial conditions.
7. Scientific Research and Teaching
As a general-purpose multi-temperature zone tubular furnace, it is used for exploratory experiments and student training in materials science, chemistry, physics, and other related fields.
