Tungsten monocrystal cutting without distortion

Electrolyte with high electric current localization, containing 1-3 % KOH and 2-10 % NH3, is suggested to use for electrochemical cutting of tungsten. A cutting device is described which includes a cathode feed mechanism based on electric heating and a circuit of automatic control of an interelectrode gap. Laue patterns obtained from a cut surface are practically the same as ones from the initial monocrystal
