A sintering electrode made of a high-melting metal (tungsten, for example) is made of a metal powder with spherical grains of a well defined grain size. The average grain size equals 5 to 70 µm. The grain size distribution fluctuates by maximum 20 % around the average grain size.
Cette électrode de frittage en un métal à haut point de fusion (par exemple le tungstène) est constituée d'une poudre métallique à grains sphériques d'une grosseur bien définie. La grosseur moyenne des grains est comprise entre 5 et 70 mu m. La distribution granulométrique oscille d'au maximum 20 % autour de la grosseur moyenne des grains.
