Abstract
The chromia-yttrium aluminum garnet long fibers were prepared by the sol–gel method using aluminum chloride, aluminum powder, yttrium oxide, chromium trioxide, and acetic acid as raw materials. The spinnability of precursor sol increased while the addition content of polyvinylpyrrolidone increased. The precursor sol has excellent spinnability at 40–60 °C. The chromium (VI) was completely reduced to chromium (III) in the preparation process of chromia-yttrium aluminum garnet fibers. A 5 wt% chromium trioxide completely dissolved in solid solution (Y3(Al1-xCrx)5O12). The chromium can hinder grain growth in yttrium aluminum garnet fibers. The grain growth exponent of the fibers was about 2.88 at 1600 °C. The chromia-yttrium aluminum garnet (Cr-YAG) long fibers were prepared by the sol–gel method using aluminum chloride, aluminum powder, yttrium oxide, chromium trioxide (CrO3), and acetic acid as raw material. A 5 wt% CrO3 completely dissolved in solid solution (Y3(Al1-xCrx)5O12). The Cr6+ can change to Cr3+ in the preparation process of Cr-YAG fibers.
