Surface tension of lead–bismuth eutectic melts with lithium

Аннотация

The temperature and concentration dependences of the surface tension of lithium alloys (up to 33.1 at %) on the basis of a eutectic melt of Pb_44.7Bi_55.3 are measured in the range from the liquidus temperature to 700 K. The margin of error of the experiments was ~2%. Lithium has a low surface activity in the Pb_44.7Bi_55.3 eutectic melt, which agrees with the criteria of the surface activity of components in binary liquid metal melts.
