Throughout this literature research report, the influence of operational conditions during bulk storage on the mechanical characteristics of various inorganic, crystalline, day-to-day salts has been investigated, in order to make a prediction on the effect of operational conditions on the mechanical characteristics of sodium borohydride. Firstly, an analysis and selection of the various mechanical characteristics has been conducted. Secondly, an analysis of the chemical properties helped to select a list of materials that are chemically similar to sodium borohydride. Thirdly, an effort was made to compare these materials to sodium borohydride using the selected mechanical characteristics. Using the particle sizes, bulk densities and angles of repose, sodium borohydride could to a certain extent be linked to calcium chloride, magnesium sulfate, potassium chloride, potassium carbonate and silicon dioxide. Lastly, an analysis on the effect of operational conditions on the mechanical characteristics of the materials has been conducted. No definitive conclusions could be drawn about the effect of the operational conditions on the mechanical characteristics of sodium borohydride.
