THE STRUCTURE AND PROPERTIES OF POROUS NICKEL PLAQUES

摘要: The structure of porous nickel plaques produced by the following routes has been examined using scanning electron microscopy: (a) pressure-less sintering powder; (b) slurry (c) roll-compaction and (d) pyrolysis cloth impregnated with chloride. observations show that measurements pore-size distribution a mercury porosimeter can be misleading, also reveal existence fine closed porosity in made from cloth. relation observed characteristics inter-particle bond diameters to mechanical electrical properties is discussed.
