Synthesizing Aluminum Particles Towards Controlling Electrostatic Discharge Ignition Sensitivity

Abstract

Aluminum particles were synthesized with shell thicknesses ranging from 2.7 to 8.3nm and a constant diameter of 95nm. These fuel particles were combined with molybdenum trioxide particles and the electrostatic discharge (ESD) sensitivity of the mixture was measured. Results show ignition delay increased as the alumina shell thickness increased. These results correlated with electrical resistivity measurements of the mixture which increased with alumina concentration. A model was developed using COMSOL for ignition of a single Al particle. The ignition delay in the model was consistent with the experimental results suggesting that the primary ESD ignition mechanism is joule heating.
