Abstract

L'invention se rapporte à un procédé permettant d'obtenir des poudres hautement dispersives de substances non organiques par explosion d'ébauches de métal au moyen d'une impulsion de courant électrique dans un milieu gazeux sous haute pression, à une densité spécifique de l'énergie appliquée à l'ébauche comprise entre 90 % de l'énergie de sublimation du métal de l'ébauche et l'énergie de sa ionisation, pendant une durée maximum de 15 msec. Une installation permettant d'obtenir des poudres hautement dispersives par ledit procédé comprend un accumulateur d'énergie électrique (2), un réacteur pour l'explosion de l'ébauche de métal (6), qui est pourvu de deux électrodes (7, 8), et d'un mécanisme d'avance de l'ébauche (9). L'une des électrodes du réacteur (8) est mise à la terre et montée à une distance de l'ébauche égale à 5-10 diamètres et à une distance du mécanisme d'avance égale à 20-40 diamètres. Pour augmenter la précision de maintien des paramètres désirés, le mécanisme d'avance de l'ébauche est équipé d'une unité de formage servant à donner à l'ébauche une forme en spirale (12). L'électrode (7) du réacteur est connectée à l'accumulateur d'énergie électrique par un commutateur (3), lequel est constitué par un diviseur de tension (4) et par un organe d'arrêt de décharge à deux électrodes (5).
