Resum
Experiments for determining nickel solubility limit and iron diffusion coefficient are presented and their results are discussed. Nickel solubility limit is determined by two methods: ex situ by solid sampling followed by ICP-AES analysis and in situ by Laser Induced Breakdown Spectroscopy and their results are compared. The iron diffusion coefficient is obtained using the technique of rotating specimen dissolution. Also a method to determine the oxygen solubility and diffusivity in LBE is developed and results at 460, 500 and 540 °C are presented. It is based on the following electrochemical cell: O2 (reference mixture), Pt //YSZ//O2 (LBE) which can work as an oxygen sensor or as a coulometric pump.
