โœฆ Synopsis


The rate of diffusion of antimony in copper single crystals has been measured over the temperature range 600'1OOO'C by means of a sectioning technique employing the Sblz4 radio-isotope as tracer. The diffusion activation eneigy and frequency factor were found to be 42000 & 700 cal mole-l and 0.34 5 0.12 cm2 see-l. This result is compared with existing data on the diffusion of impurity atoms in copper.

DIFFUSION

DE L'ANTIMOINE DANS DES MONOCRISTAUX DE CUIVRE Les auteurs ont mesure la vitesse de diffusion de l'antimoine dans des monocristaux de cuivre pour une gamme de temperatures comprises entre 600 et lOOO"C, en utilisant une technique de coupe qui fait intervenir le radio-isotope Sbla4 comme traceur. L'Bnergie d'activation de diffusion et le facteur de frbquence sont de 42000 f 700 cal m8le-l et 0.34 & 0,12 cm2 set-l. Ce r&&at est compare avec les don&es existantes sur la diffusion d'atomes d'impuret& dans le cuivre. DIE DIFFUSION VON ANTIMON IN KUPFEREINKRISTALLEN Die Diffusionsgeschwindigkeit von Antimon in Kupfereinkristallen wurde im Temperaturbereich von 600" bis 1000ยฐC mit Hilfe einer Trenntechnik bestimmt, wobei das Isotop Sb1'J4 als radioaktives Spurenelement beniitzt wurde. Die Aktivierungsenergie der Diffusion und der Frequenzfaktor ergaben sich zu 42000 f 700 cal/Mol und 0,34 f 0,12 cm8 se@. Dieses Ergebnis wird verglichen mit vorhandenen Daten iiber die Diffusion von Verunreinigungsatomen in Kupfer.
