Effects of Boric Acid Addition on Microstructure of Yttrium Aluminum Garnet AITranslate
Abstract AITranslate
Yttrium aluminum garnet （YAG） ceramic fibers were prepared by sol-gel with aluminum chloride,aluminum powder,yttrium oxide and acetic acid as raw materials. Boric acid was added into YAG precursor sol to study the effects of boric acid on the spinnability of sol,and crystallization temperature and microstructure of YAG fibers. The results indicate that addition of boric acid has no effect on the sol spinnability. Upon 2 h calcination at 1 000 ℃ ,YAG gel fibers are fully crystallized into YAG. The addition of boric acid can improve the fiber crystallization and decrease the crystallization temperature. Larger grains and intergranular voids can be observed on the surface of the fibers with boric acid.
