Abstract

Generation of microdischarges inside porous ceramics by AC high voltage was explored. The physical properties of the microdischarges were investigated by electrical measurements, photographic visualization, and optical emission spectroscopy. The effects of pore size, discharge
power, and gas mixture composition on the discharge properties and its development are described. The optimumgeneration and distribution of
the microdischarges was observed with pore sizes of 50 and 80 mm. The emission spectra of themicrodischarges indicated their strongly non-equilibrium character. A theoretical analysis of the microdischarge mechanism is provided, accounting for the pore size and the elementary
processes such as ionization, recombination, and ambipolar diffusion.
