Reaction onset temperature
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 … WebThese observations highlight the importance of the nascent halide salt product in determining the reaction onset temperature, which is lower for all studied cometathesis reactions than the reaction temperatures of the constituent single-ion metathesis reactions. In addition, the spectating alkali and alkaline earth species determine the ...
