酸化剤とZr/Ni合金混合系の電気火花感度(物質生命化学科)

Abstract

This study was carried out to obtain thermal and ignition sensitivity of the mixture of KClO_4 and Zr/Ni alloy. This mixture shows the violent exothermic reaction. It was suggested the rate determining step of the thermal ignition of the mixture is the ignition of Zr in Zr/Ni alloy. As the electrostatic discharge test, approaching electrode and CR probe plate methods were used. Ignition sensitivity of Zr/Ni alloy by approaching electrode and probe plate methods was less sensitive than that of Zr. The 50% minimum energy of ignition by the CR probe plate method was more sensitive than by the approaching electrode method. Thermal reaction scheme was deduced as; Zr/Ni+KClO_4→ZrO_2+NiO+KCl+1/2O_2.
