A contrast test of sintered wicks with different particle size of Cu powder and different pore-forming material(CuCl2·2H2O,NaCl) and content was conducted.The porosity,permeability and compressibility were measured.The pore morphology and sintering neck were characterized with field emission scanning electron microscope(FESEM),the mechanism of sintering aggrandizement in hydrogen reduction atmosphere were discussed.Experimental results show that the porosity,maximum pore size and permeability of sintered wi...
