Abstract
A substantially non-explosive mixed powder containing finely divided metallic particles suitable for being incorporated in a refractory mixture, intimately mixed together with inert refractory particles. The refractory particles are present in such particle sizes and quantities as ensure that the Minimum Explosible Concentration, as tested in a 20-L vessel with a chemical igniter, is greater than 100 gm/m.sup.3. The inert particles comprise at least 40% of the mixture, and preferably 50% to 80%. The invention also includes a premixed powder, of the metallic and refractory powder, especially as contained in a shipping container in drums or impermeable bags. Due to the presence of the refractory powder, the mixed powder can be shipped without the precautions usually needed for shipping finely divided metal powders.
