Have you ever wondered how materials reveal their inner dynamics under the microscopic gaze of an electron microscope as temperatures rise? From phase transitions to grain growth and oxidation reactions, real-time observation of these dynamic processes is crucial for understanding material properties. TESCAN's Murano™ Heating Stage is transforming this vision into reality, opening new dimensions in metallurgical and materials science research.

Direct observation of sample changes during heating within a scanning electron microscope (SEM) is key to revealing materials' intrinsic mechanisms. The Murano™ Heating Stage makes this possible by dynamically displaying phase transitions, recrystallization, grain growth, and oxidation processes during heating, allowing researchers to "see" materials' life cycles. Its unique thermal isolation interface design enables easy integration with most standard SEM sample stages, perfectly compatible with SEM imaging, electron backscatter diffraction (EBSD), and focused ion beam (FIB) processing for multidimensional research.

The Murano™ Heating Stage covers temperatures from ambient up to 950°C, meeting diverse material research needs. For enhanced applications in catalysis, reduction, or oxidation studies, it offers an optional gas injection system. Precise gas control is achieved through a capillary near the sample, with external flow adjustable via flange-mounted needle valves. To ensure SEM safety, the stage features an efficient water-cooled base and protective shield, safeguarding the chamber and detectors from high temperatures. Each system includes a low-vibration water chiller with safety flow switches, power supply, and PC-based temperature controller interlock for stable, secure operation.

During high-temperature SEM analysis, thermal electrons often interfere with secondary electron collection, affecting image quality. The Murano™ Heating Stage integrates bias control on the interface flange to suppress thermal electrons while enhancing secondary electron extraction, delivering clear, high-quality images even at elevated temperatures—critical for capturing subtle structural changes.

The stage's heating platform uses a consumable design for easy replacement, significantly improving experimental efficiency. Its logging software precisely correlates timestamps with temperature data for subsequent analysis. When paired with the DigiScan™ digital beam control and imaging system, temperature data can be directly overlaid on recorded images and videos through in-situ video software, providing unprecedented visualization of thermal processes.
