Abstract

La présente invention concerne : des particules de cuivre métallique présentant d'excellentes propriétés de frittage à basse température à des températures inférieures ou égales à 300 °C ; et leur procédé de production. Dans ces particules de cuivre métallique, des particules fines de cuivre métallique sont collées aux surfaces de particules de cuivre métallique de grand diamètre. En ce qui concerne les particules de cuivre métallique devant être produites, de l'oxyde de cuivre et de l'acide hypophosphoreux et/ou un sel de ceux-ci sont mélangés et réduits, de préférence en présence de 1 à 500 % en masse de gélatine et/ou de peptide de collagène. La température de la réaction de réduction est de préférence située dans la plage allant de 20 à 100 °C. Les particules de cuivre métallique produites présentent une valeur de résistivité transversale, une fois chauffées à une température de 300 °C sous une atmosphère d'azote, inférieure ou égale à 1 × 10-2 O·cm.
