翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Pyroceram ： ウィキペディア英語版 Pyroceram Pyroceram is the original glass-ceramic material developed and trademarked by Corning Glass in the 1950s.〔M. Montazerian, S.P. Singh & E.D. Zanotto, "An Analysis of Glass-Ceramic Research and Commercialization," ''American Ceramic Society Bulletin'', Vol. 94, #4, p 30-35 (2015).〕 ==Development== Its development has been traced to Corning's work in developing photosensitive glass. Corning credits S. Donald Stookey with its discovery; while conducting research in 1953 on a photosensitive lithium silicate glass called Fotoform containing a dispersion of silver nanoparticles, Stookey noted that an accidentally overheated fragment of the glass resisted breakage when dropped.〔(【引用サイトリンク】publisher=Corning Glass )〕 Stookey's initial glass-ceramic became Fotoceram, with Li2Si2O5 and quartz as its crystalline phases. Fotoceram evolved into Pyroceram in 1959, with β-spodumene as the crystalline phase, which evolved into the CorningWare line of cookware.〔W.W. Shaver & S.D. Stookey, "Pyroceram," ''SAE Technical Papers'', 90428, 1959.〕 The manufacture of the material involves controlled crystallization.〔 NASA classifies it as a glass-ceramic product.〔(【引用サイトリンク】url=http://gltrs.grc.nasa.gov/reports/2003/TM-2003-212487.pdf )〕 After about 30 years of informal use as a standard in high heat (≥1000°C) applications, Pyroceram 9606 was approved by NIST as a certified reference material for thermal conductivity measurements. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pyroceram」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
