Reaction onset temperature
WebAug 22, 2016 · By contrast, reaction onset temperature is associated with a chemical reaction with negligible self-heating involved. This occurs for systems with very large surface-to-volume ratios such that the temperatures of the system and its surroundings remain nearly equal. WebJun 29, 2024 · The onset transition temperature of the Cl-added YBCO sample was about 89.5 K, which was slightly larger than that of the Cl-free YBCO sample at 88.6 K. With the addition of Hf, the onset transition temperature of the samples decreased slightly. Overall, the addition of Cl did not much change the superconducting transition temperature of …
