A new approach for in-situ studying the phase transition of paramagnetic materials: High-temperature Faraday Balance

Based on the principle of the susceptibility transformation in the phase transition of paramagnetic material, the high-temperature Faraday Balance can observe the dynamic process in the phase transition of material. We utilize it measuring the susceptibility variation of Ag₂O and CuO at high temperature. It reveals the dynamic decomposing process in the melting of Ag₂O and the solidification of Ag, as well as the decomposition and halfway synthesis reaction of CuO. By the two examples, we introduce this new approach for studying the phase transition of paramagnetic materials-high-temperature Faraday Balance. This method provides a reliable experimental data for the materials' fabricating process.
