Abstract
Many powder materials in bulk form can exhibit self-heating when subjected to high temperature conditions. Self-heating of powder could be a potential ignition source for a fire and/or explosion event in addition to affecting the product quality and creating environmental issues. Understanding the behavior of the product in powder or granular form is the first step in controlling the risks associated with self-heating. This article provides an overview to the self-heating phenomena and discusses experimental techniques used to understand powder behavior that are subjected to high temperature conditions. The article focuses on test methods that can be used to determine the onset temperature for self-heating of powders under varying experimental conditions.
