Preparation of a material for producing electrical contact pellet, where the material comprises a silver based alloy matrix conductor containing a reinforcement made of ceramic compound (e.g. tin oxide) and a doping agent (e.g. copper oxide) to improve the electrical performances, comprises: synthesizing a powder containing reinforcement coated with doping agent; deagglomerating the reinforcement particles contained in the powder, by attrition; mixing the deagglomerated powder in a silver nitrate solution; obtaining a powder containing silver oxide particles; and reducing silver oxide. Preparation of a material for producing electrical contact pellet, where the material comprises a silver based alloy matrix conductor containing a reinforcement made of ceramic compound (tin oxide, cadmium oxide, iron (I) carbonate, zinc oxide, zirconium oxide, zirconium boride, tungsten or tungsten carbide) and a doping agent (copper oxide, tungsten trioxide, molybdenum trioxide, bismuth oxide, antimony oxide, tellurium dioxide, ruthenium oxide, magnesium oxide, germanium (IV) oxide, tantalum pentoxide, zinc oxide, iron (I) carbonate, niobium pentoxide or tantalum carbide powder) to improve the electrical performances, comprises: synthesizing a powder containing reinforcement coated with doping agent, where the reinforcement particles have a sub-micron size, diameter of the particles is less than 1 mu m; deagglomerating the reinforcement particles contained in the powder, by attrition; mixing the deagglomerated powder in a silver nitrate solution; obtaining a powder containing silver oxide particles and reinforcement particles in which the doping agent is diffused and nitrate is neutralized by a base, by a chemical engineering process; reducing silver oxide by calcining, where the temperature of calcination is greater than 500[deg] C; and obtaining a powder containing silver mixed with reinforcement particles. An independent claim is included for a pellet for contact in the material, where the material is obtained by the process and the material contains more than 90% of particles of submicronic size, particles composed of tin oxide coated with copper oxide, and the diameter of coated tin oxide particles is less than 1 mu m.
