第二篇: Effect of nano-Nd2O3 on Sintering and Crystallization of Fused Quartz Ceramic Materials PROGRESS IN MATERIALS AND PROCESSES, PTS 1-3 叢書: Advanced Materials Research 卷: 602-604 頁: 499-502 DOI: 10.4028/www.scientific.net/AMR.602-604.499 出版年: 2013 會議名稱 會議: 2nd International Conference on Materials and Products Manufacturing Technology (ICMPMT 2012) 會議地點(diǎn): Guangzhou, PEOPLES R CHINA 會議日期: SEP 22-23, 2012 會議贊助商:Inner Mongolia Univ Technol; Korea Maritime Univ; Queensland Univ Technol 摘要 Fused quartz powder (d(50)=19 mu m) was used as raw material, and nano-Nd2O3 was used as additive with dosages of 1% (in mass, similarly hereinafter), 2% and 3%. The effects of nano-Nd2O3 on crystallization and sintering behavior of the materials at various temperatures (1300 degrees C/1h, 1350 degrees C/1h and 1400 degrees C/1h) were studied by measurements of apparent porosity, bending strength and thermal expansion ratios (RT similar to 1200 degrees C), and analyses of XRD and SEM. The results of XRD and thermal expansion ratios analysis showed that 3% nano-Nd2O3 additive had excellent effect on inhibiting crystallization of the samples sintered at 1350 degrees C and 1400 degrees C. The results showed that the samples sintered at various temperatures with 3% nano-Nd2O3 had the lowest apparent porosity and more compact microstructure. This indicated that 3% nano-Nd2O3 had better effect on facilitating sintering of fused quartz materials. 關(guān)鍵詞 作者關(guān)鍵詞:fused quartz; nano-Nd2O3; crystallization; Sintering; thermal expansion 作者信息 通訊作者地址: Gu, YL (通訊作者) Hebei United Univ, Coll Mat Sci & Engn, Hebei Prov Key Lab Inorgan Nonmetall Mat, Tangshan 063009, Peoples R China. 地址: [ 1 ] Hebei United Univ, Coll Mat Sci & Engn, Hebei Prov Key Lab Inorgan Nonmetall Mat, Tangshan 063009, Peoples R China 電子郵件地址:mmmgyl@163.com; bjl@heuu.edu.cn; yulx@heuu.edu.cn; chenjunxinglaoda@163.com; wangzf@heuu.edu.cn 出版商 TRANS TECH PUBLICATIONS LTD, LAUBLSRUTISTR 24, CH-8717 STAFA-ZURICH, SWITZERLAND 類別 / 分類 研究方向:Engineering; Materials Science Web of Science 類別:Engineering, Manufacturing; Materials Science, Multidisciplinary 文獻(xiàn)信息 文獻(xiàn)類型 roceedings Paper語種:English 入藏號: WOS:000319233800103 ISBN:978-3-03785-543-0 ISSN: 1022-6680 其他信息 IDS 號: BFD19 Web of Science 核心合集中的 "引用的參考文獻(xiàn)": 10 Web of Science 核心合集中的 "被引頻次": 0 |
