Abstract (en)
[origin: DE19652822A1] 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 mu m. The grain size distribution fluctuates by maximum 20 % around the average grain size.
