Effect of titania on yttrium aluminum garnet fibers morphology developmentAuthor(s): Tan Hongbin
The titania-YAG (yttriumaluminumgarnet) fibers were prepared by sol-gel method using aluminum chloride, titanium chloride, aluminum powder, yttriumoxide and acetic acid as raw materials. The effects of titania on the YAG fiber morphology development were studied. The result indicated titania could promoteYAG grain growth. Titania-YAG fibers were obtained by sintering at 1000ï°C for 2 hours, with fine grain. But the fibers were obtained by sintering at 1400ï°C for 6 hours, with rough surface and coarse grains.
