用静电悬浮法结合振荡滴技术测量了2325 ~ 2556 K温度范围内液态硼的粘度。结果表明，在2550 K ~ 2370 K温度范围内，粘度随温度的降低而缓慢增加，在低于熔融温度时，粘度随温度的进一步降低而显著增加，到2325 K时，粘度达到最大值。粘度的增加表明硼的过冷液体中可能出现具有伸展的团簇。
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 fromat 2550 K toat 2370 K, and substantially increases with further decrease in temperature below the melting temperature, becoming as large asat 2325 K. The increase in the viscosity suggests that clusters with extension may appear in supercooled liquid of boron.
