The surface tension of Zr-O alloys was measured by a non-contact method. There was excellent agreement with literature data for Zr + 57 ppm oxygen, confirming the accuracy of our measurements. The samples of 57 ppm and 1560 ppm O show no statistically significant change in surface tension within the resolution of our experiment, 0.87%. This result is consistent with the measurement at higher oxygen content. For higher oxygen, the dependence was 3.72%/%O.
