In cutting-edge fields such as ultra-high-temperature material synthesis, aerospace thermal protection system validation, and nuclear reactor material service evaluation, ultra-high-temperature environments (>1500°C) have become a core enabler of breakthrough technological development.

However, traditional resistive heating faces two major bottlenecks:

Limited Heating Rates: Conventional resistance furnaces typically achieve heating rates below 200°C/min.

Inadequate Temperature Limits: Constrained by the melting point and oxidation loss of heating elements, resistive heating is often limited to effective working temperatures below 1500°C, unable to meet the synthesis and testing needs of materials such as high-temperature alloys.

These limitations result in a lack of high-temperature phase transition kinetic data and insufficient validation of extreme thermal shock service performance, severely hindering material development progress.

To address these challenges, Guoguo Instrument introduces the Infrared Ultra-High-Temperature Heating System, delivering a precisely controlled extreme thermal environment:

• Utilizes infrared radiation sources combined with reflector focusing technology, achieving maximum temperatures of 1700°C (up to 1800°C). Heating rates are significantly improved, reaching 30°C/s. Based on high-precision PID algorithms, it dynamically adjusts radiation power to ensure temperature stability within ±0.1°C at high temperatures.

• Equipped with a vacuum pump and gas exchange unit, enabling experiments under extreme conditions in vacuum, standard atmospheric pressure, or controlled gas environments.

• Supports custom multi-segment heating and cooling programs.

• To enable full-process observation of high-temperature processes, the system can be integrated with microscopic optical systems, high-temperature Raman systems, and more.

※ Ultra-High-Temperature Microscopy System

1）Modular Design: Allows future upgrades for in-situ testing capabilities such as Raman spectroscopy.

2）Auto-Focusing: Electric objective lifting and lowering mechanism.

3）405nm Monochromatic Köhler Illumination and Imaging: Suppresses long-wavelength background from blackbody radiation, enhancing image clarity. Illumination provides uniform field coverage without dark corners.

4）Control Software: Integrated control for mechanical adjustments, light source control, microscopic imaging and saving, auto-focusing, and more.

※ Ultra-High-Temperature Raman Testing System (Compatible with Timegate Raman)

Leveraging time-gated detection technology (nanosecond-level time gating), the system captures material-specific Raman signals during heating intervals while filtering out long-wavelength blackbody radiation. This enables successful in-situ analysis of ceramic lattice vibration modes at 1700°C.
