Thermal Analysis

National Laboratory: 
Pacific Northwest National Laboratory
Characterization Class: 
Extreme Environment Testing
Description: 

Two MettlerToledo high-throughput high-temperature-capable thermal analyses, a differential scanning calorimetry (DSC) and a thermogravimetric analysis (TGA), are available within this capability. For thermal analysis, PNNL also offers one magnesium-specific Netzsch DSC/TGA, two general material Netzsch DSC/TGAs, DTA (differential thermal analysis)/TGA, and TGA-only systems. Netzsch and Anter high-temperature capable dilatometers can be used for determining thermal expansion.

Capability Bounds: 

High-throughput high-temperature DSC/TGAs can automatically test up to 32 samples to temperatures up to 1600°C at heating rates up to 150°C/min. in air or inert gases. The magnesium-specific DSC/TGA can test samples from -120 to 675°C in inert gas with heating and cooling rates of up to 50°C/min. General sample DSC/TGA, DTA/TGA, and TGA only have capabilities from -120 to 1600°C at heating and cooling rates up to 50°C/min. Both Netzsch horizontal and Anter vertical dilatometers are high-temperature capable up to 1600°C with heating rates up to 50°C/min.

Unique Aspects: 

High-throughput DSC/TGA can automatically run 32 samples at a time up to 1600°C. The magnesium-specific DSC/TGA is dedicated to that material and its issues with volatility.

Availability: 

Systems are available to augment projects.
