Abstract—The I–V characteristics of a zeolite (clinoptilolite)–10% silicon powder mixture at different air pres-
sures in the chamber are taken. In a constant electric field, the current is found to be stationary in contrast to
pure zeolite powder, where the current decays with time. In the case of the stationary current, the I–V charac-
teristic consists of a high-resistivity portion at low voltages and a low-resistivity portion at high voltages. The
latter portion is identified as the gas-discharge current. A discharge initiation mechanism in which silicon par-
ticles play a decisive role is suggested.
