“…The melting point of lutetium oxide (Lu 2 O 3 ) is as high as 2490 ℃, and there is no phase transition below the melting point [1][2][3][4]. The characteristics of corrosion resistance, low phonon energy [5], and high structural tolerance make it promising in the fields of refractory materials [6], catalytic materials [7], superconductivity [8], optics [9][10][11][12][13][14], magnetic materials [10], and highenergy radiation detection [13]. Especially in optics, Lu 2 O 3 has received extensive attention as a promising scintillator candidate material.…”

The difficulty of reducing the diameter of lutetium oxide (Lu 2 O 3 ) continuous fibers below 50 μm not only limits the flexibility of the sample but also seriously affects their application and development in high-energy lasers. In this work, a Lu-containing precursor with high ceramic yield was used as raw material, fiberized into precursor fibers by dry spinning. The pressure-assisted water vapor pretreatment (PAWVT) method was creatively proposed, and the effect of pretreatment temperature on the ceramization behavior of the precursor fibers was studied. By regulating the decomposition behavior of organic components in the precursor, the problem of fiber pulverization during heat treatment was effectively solved, and the Lu 2 O 3 continuous fibers with a diameter of 40 μm were obtained. Compared with the current reported results, the diameter was reduced by about 50%, successfully breaking through the diameter limitation of Lu 2 O 3 continuous fibers. In addition, the tensile strength, elastic modulus, flexibility, and temperature resistance of Lu 2 O 3 continuous fibers were researched for the first time. The tensile strength and elastic modulus of Lu 2 O 3 continuous fibers were 373.23 MPa and 31.55 GPa, respectively. The as-obtained flexible Lu 2 O 3 continuous fibers with a limit radius of curvature of 3.5-4.5 mm had a temperature resistance of not lower than 1300 ℃, which established a solid foundation for the expansion of their application form in the field of high-energy lasers.
