The surface tensions of C0 2‐ laser‐melted alumina‐containing liquids have been measured by a static, pendant‐drop technique in air, helium, and a 90% helium‐10% hydrogen mixture. The influences of up to 10 wt% Cr 2 0 3 , MgO, and TiO 2 have been studied. Surface tension data are also reported throughout the whole concentration range between liquid alumina and zirconia in air. A new analytical technique based on comparing calculated and observed melt contours is reported. Using this technique, more precise surface tension to density ratios can be determined from low length to diameter ratio pendant drops than by previously reported procedures.
