The Phase Transformation of R2O-CaO-SiO2-F Glass-ceramics宋树欣Key Laboratory of Silicate Materials Science and Engineering (Wuhan University of Technology),Ministry of Education摘 要:The phase transformation of R2O-CaO-SiO2-F system glass-ceramics with various additions of K2O and F was investigated by DTA, XRD, SEM and other techniques. The crystallization......
Synthesis of YAG:Ce3+ Phosphor by Polyacrylamide Gel Method and Promoting Action of α-Al2O3 Seed Crystal on Phase Formation Cheng Changming1,Wu Yanli1,Gu Ziying1,Min Yulin1,Zhou Xuezhen1,Li..., are formed when calcining polyacrylamide gel, however, the pure YAG phase can be formed directly when calcining polyacrylamide gel with α-Al2O3 as seed crystal. These facts show that the existence......

Spraying (LPPS). Microstructure characteristics and phase compositions of the coatings were studied by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively.... Besides WC phase, there was W2C phase. However in the coating deposited by LPPS the content of oxygen was so low that there were a limit degradation of the WC/12Co powder. The coatings were made up......
