Research on Preparation Process of Polycrystalline Yttrium Aluminum Garnet Fiber AITranslate
Abstract AITranslate
The polycrystalline yttrium aluminum garnet （YAG） fibers were prepared with sol-gel method. The investigations were made of the viscosity, spinnability,infrared absorption characteristics and thermal decomposition properties of the YAG sol. Meanwhile, the phase structure and microstructure of the YAG fiber were analyzed. The results show that the spinnability of the YAG sol is the best when the solid content of the sol is 26%-28% and the spinning temperature is 20 ℃ There are lots of hydroxyl groups of Al-OH and Y-OH exsiting in the YAG sol,and the two kinds of hydroxyl groups can be condensed to form macromolecular chains by losing H2 O, macroscopically exhibiting the spinnability. Weight-loss of the YAG sol mainlY occurs below 600 ℃ in the thermal decomposition process. The YAG fibers with pure phase can be obtained with sol-gel method. The YAG fiber grains grow up gradually as the calcination tem- perature and time increase, resulting in the quantity and size increase of the holes among grains and property degradation of YAG fiber.
