Laser spectroscopic studies of gas diffusion in alumina ceramics

Zhang, Hao and Svanberg, Sune LU (2016) In Optics Express 24(3). p.1986-1998
Abstract

Experiments for measuring gas diffusion through porous alumina ceramics are described. With the gas in scattering media absorption spectroscopy (GASMAS) technique, gaseous oxygen signals are measured continuously during the gas diffusion process. It is experimentally demonstrated that the time-dependence of the transient oxygen signal is described by an exponential curve. Moreover, the effect on gas diffusion of material porosity and whether water is present or not is also experimentally investigated.
