This material is an industry standard for the manufacture of sintered electrodes used in nickel battery production, due to its controlled porosity. It is also used as a pigment for the production of electrically conductive coatings and in a number of powder metallurgical appplications.
Standard packaging is 75kg but Hart Materials can supply in smaller packs down to 5kg, depending on individual customer requrements.
