翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Perhamite ： ウィキペディア英語版 Perhamite Perhamite is a phosphate mineral with the formula Ca3Al7(SiO4)3(PO4)4(OH)3·16.5(H2O). It occurs in rare isolated masses in amblygonite-rich pegmatite deposits throughout the world. It was discovered in platy sheed form of 1mm hexagonal crystals.〔Mills,S., Mumme, G., Grey, I. and Bordet, P.(2006): The crystal structure of perhamite. Mineralogical Magazine 70,201-209〕〔Frost, Ray L., Matt L. Weier, and Stuart J. Mills. (2007)A Vibrational Spectroscopic Study of Perhamite, an Unusual Silico-Phosphate, Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy 67.3, 604-10〕 It was first described in 1977 by P.J. Dunn and D.E. Appleman〔Dunn, P. and Appleman, D.: Perhamite, a new calcium aluminum silico-phosphate mineral and a re-examination of viseite. Mineralogical Magazine 41, 437-442〕 from pegmatite collected from Bell Pit, Newry, Maine. Other specimens have been found in Kapunda, South Australia, in Silver Coin mine near Humboldt County, Nevada〔 and various locations throughout Europe.〔 ==Composition== The formula〔 Ca3Al7(SiO4)3(PO4)4(OH)3·16.5(H2O) was determined by measuring its composition with x-ray spectroscopy giving the average amounts of SiO2 to be 13.72%, Al2O3 to be 27.17%, CaO to be 12.81%, P2O5 to be 21.61%, leaving 24.69% to be determined as H2O〔Mills, S. (2003): A note on perhamite from the Moculata( Klemms)phosphate quarry, South Australia, Australia. J. Mineral. 9, 43-45〕 The formula's essential elements are Al, Ca, H, O, P and Si with trace amounts of Sr. Common impurities of perhamite include Ti, Fe, Mg, Na, and F.〔 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「Perhamite」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.
