Viscosity of liquid boron was measured over the temperature range from 2325 to 2556 K using an electrostatic levitation method combined with an oscillation drop technique. The results obtained revealed that the viscosity increases slowly with decreasing temperature from 2.2 mPas at 2550 K to 2.6 mPas at 2370 K, and substantially increases with further decrease in temperature below the melting temperature (Tm =2360 K), becoming as large as 6.4 mPas at 2325 K. The increase in the viscosity suggests that clusters with extension may appear in supercooled liquid of boron.
