The tests were performed using a TGA 5500 system under an air atmosphere, with platinum pans and a 10 Hz sampling rate. Each test includes multiple thermal segments, typically involving equilibration, isothermal holds, and heating ramps up to 500-600 C. Data for each ionic liquid include time (min), temperature (C), sample weight (mg), and normalized weight (%). All samples were tested in 2023, with masses ranging from approximately 13 to 36 mg. The dataset supports broader project objectives to characterize the thermal and physical behavior of novel ionic liquid formulations intended for geothermal applications.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://gdr.openei.org/files/1768/TGA%20Metadata.txt", "description": "This file provides details of the dataset and specific files it contains.
