Overview
The MakeWave MKG-M2HB is a high-precision microwave-heated tube furnace engineered for rapid, uniform, and controllable high-temperature processing of advanced materials under inert, reactive, or vacuum atmospheres. Unlike conventional resistance-heated tube furnaces, the MKG-M2HB utilizes continuous non-pulsed 2450 MHz microwave energy to directly couple with dielectric and conductive materials—enabling volumetric heating, reduced thermal gradients, and accelerated ramp rates. Its integrated tubular architecture accommodates Φ50 mm quartz or alumina reaction tubes, supporting both static and dynamic gas-flow configurations. Designed for R&D laboratories in materials science, catalysis, battery electrode synthesis, and ceramic sintering, the system delivers reproducible thermal profiles up to 1200°C while maintaining strict process integrity across atmospheric, vacuum, and multi-gas environments.
Key Features
- Continuous-wave 1600 W microwave source operating at 2450 MHz, with fully adjustable power output (0–100%) for precise energy delivery.
- Hermetically sealed 304 stainless steel resonant cavity with embedded multi-layer insulation: low-εr ceramic fiber composites (thermal conductivity ≈ 0.226 W/m·K) minimize radial heat loss and enhance energy efficiency at elevated temperatures.
- Integrated Φ50 mm tube-compatible hot zone, optimized for side-insertion configuration; supports interchangeable quartz, alumina, or silicon carbide tubes per application requirements.
- Direct-in-situ temperature monitoring via calibrated K-type thermocouple positioned within the tube, enabling real-time feedback control of both setpoint temperature and microwave power.
- Modular atmosphere management: standard vacuum interface (–0.099 MPa), optional multi-channel mass flow controller (MFC) integration, and configurable exhaust routing for tail-gas capture or venting.
- Industrial-grade PLC-based control system with 7-inch resistive touchscreen HMI; stores up to 20 programmable thermal cycles with time-temperature-power logging and USB-exportable CSV data files.
Sample Compatibility & Compliance
The MKG-M2HB accommodates solid powders, pellets, thin films, and fiber samples housed in standard 20 mL boat crucibles (alumina, quartz, or graphite). Its Φ50 mm internal geometry permits uniform exposure to microwave fields while preserving chemical purity during annealing, carburization, nitridation, or reduction processes. The furnace meets ISO 9001:2015 quality management standards and complies with IEC 61000-4-3 (EMC immunity) and GB 10685-2003 (microwave radiation safety), with verified leakage <5 mW/cm² at 5 cm distance—exceeding international occupational exposure limits. Vacuum and gas-handling components conform to ISO 2859-1 sampling plans for leak-tightness verification; all flanges employ conductive compression gaskets to maintain EMI shielding integrity.
Software & Data Management
The embedded control firmware implements closed-loop PID regulation of temperature and microwave power, synchronized at 100 ms intervals. Real-time curves for temperature, power, and elapsed time are displayed simultaneously on the HMI and archived with timestamps. Data export supports GLP-compliant traceability: each experiment file includes operator ID, program name, version stamp, and checksum-verified metadata. Optional Ethernet connectivity enables remote monitoring via Modbus TCP or OPC UA protocols, facilitating integration into centralized lab information management systems (LIMS) and supporting FDA 21 CFR Part 11 audit trail requirements when paired with user-authenticated login and electronic signature modules.
Applications
- Synthesis and activation of cathode/anode materials for Li-ion and solid-state batteries (e.g., NMC, LFP, Si/C composites).
- Controlled pyrolysis of MOFs and COFs under nitrogen or argon for porous carbon frameworks.
- Rapid thermal annealing of 2D transition metal dichalcogenides (TMDs) and perovskite precursors.
- Vacuum-assisted graphitization of carbon nanofibers and biochar.
- Catalyst regeneration and sulfidation studies under H2/H2S mixtures.
- High-throughput screening of ceramic sintering kinetics using stepwise isothermal holds.
FAQ
Can the MKG-M2HB operate under hydrogen or ammonia atmospheres?
Yes—provided appropriate gas-handling accessories (explosion-proof MFCs, flame arrestors, and leak-tested stainless-steel lines) are installed and local safety regulations are followed.
Is the temperature measurement traceable to NIST standards?
The integrated K-type thermocouple is factory-calibrated; users may perform field recalibration using certified reference thermocouples per ASTM E230/E230M.
What maintenance is required for the magnetron and waveguide system?
No routine magnetron servicing is needed within the first 5,000 operational hours; periodic inspection of waveguide arcing points and cooling fan performance is recommended annually.
Does the system support automated ramp-soak-cool sequences with dwell stabilization?
Yes—up to 10 segment programs with independent rate, soak time, and power modulation per segment are supported.
Can third-party software interface with the PLC for custom scripting?
Yes—the Modbus TCP register map is documented in the technical manual, enabling integration with Python, LabVIEW, or MATLAB-based automation platforms.
