Kuvarstaki ana safs\u0131zl\u0131k elementleri Al, Fe, Ca, Mg, Li, Na, K, Ti, B, H’dir. Safs\u0131zl\u0131k elementleri, alkali metaller, ge\u00e7i\u015f gibi y\u00fcksek safl\u0131kta kuvars \u00fcr\u00fcnlerinin kalitesi \u00fczerinde b\u00fcy\u00fck bir etkiye sahiptir. metaller, Al ve P, vb. Element i\u00e7eri\u011fi, y\u00fcksek safl\u0131kta kuvars hammaddelerinin \u00f6nemli bir g\u00f6stergesidir. Safs\u0131zl\u0131k elementlerinin i\u00e7erik gereksinimleri, haz\u0131rlanan kuvars cam\u0131n kullan\u0131m\u0131na g\u00f6re de\u011fi\u015fir, ancak genel e\u011filim, ne kadar d\u00fc\u015f\u00fck olursa o kadar iyidir.<\/p>\n

(1) Alkali metal elementler Li, K, Na<\/p>\n

Kuvars cam\u0131n servis s\u0131cakl\u0131\u011f\u0131n\u0131 ve mekanik g\u00fcc\u00fcn\u00fc azalt\u0131n ve kuvars cam\u0131n kristalle\u015fmesini y\u00fcksek s\u0131cakl\u0131kta katalize ederek, kuvars cam\u0131n devitrifikasyonu ve y\u00fcksek s\u0131cakl\u0131k deformasyonu ile sonu\u00e7lan\u0131r. Alkali metal elementlerin i\u00e7eri\u011finin azalt\u0131lmas\u0131, y\u00fcksek safl\u0131kta kuvars potan\u0131n yumu\u015fama noktas\u0131n\u0131 artt\u0131rmak, kuvars potan\u0131n deformasyon direncini artt\u0131rmak ve tek kristallerin verimini artt\u0131rmak i\u00e7in faydal\u0131d\u0131r.<\/p>\n

IOTA standart kum, alkali metal elementlerin toplam\u0131n\u0131n 2.4\u00d710-6 olmas\u0131n\u0131 gerektirir ve proses t\u00fcpleri, silikon gofret i\u015fleme, kuvars bloklar ve tek kristal silikon i\u00e7in yar\u0131 iletken potalar i\u00e7in gereken y\u00fcksek safl\u0131kta kuvars, <1.4\u00d7 toplam\u0131n\u0131 gerektirir. 10-6, CZ Tipi pota, toplam\u0131 <0.5 \u00d7 10-6 gerektirir ve 12 in\u00e7 veya daha b\u00fcy\u00fck silikon gofretler i\u00e7in ultra y\u00fcksek safl\u0131kta kuvars kumu, toplam\u0131 <0.08 \u00d7 10-6 gerektirir.<\/p>\n

(2) Ge\u00e7i\u015f metali elementleri Cr, Cu, Fe<\/p>\n

Kuvars cam, \u0131\u015f\u0131k ge\u00e7irgenli\u011fini etkileyen ve cihaz\u0131n g\u00fcvenilirli\u011fini ve kararl\u0131l\u0131\u011f\u0131n\u0131 azaltan renkli noktalar \u00fcretir veya kuvars cam\u0131n y\u00fcksek s\u0131cakl\u0131kta renk bozulmas\u0131na neden olur. Optik fiberlerin uygulanmas\u0131nda mikroskobik d\u00fczensizli\u011fe neden olacak, fiber kayb\u0131n\u0131 art\u0131racak ve hatta sinyal bozulmas\u0131na yol a\u00e7acakt\u0131r. Yar\u0131 iletken uygulamalar\u0131nda, \u00fcr\u00fcndeki \u00e7ok az miktarda ge\u00e7i\u015f metali elementi kristal b\u00fcy\u00fcmesini destekleyebilir.<\/p>\n

(3) Al ve P<\/p>\n

Kuvars kafesine girmek, kuvars \u00fcr\u00fcnlerinin iletkenli\u011fini etkileyecek ve ayn\u0131 zamanda kuvars cam\u0131n kristalle\u015fme etkisini art\u0131racak ve hizmet \u00f6mr\u00fcn\u00fc azaltacak g\u00fc\u00e7l\u00fc kimyasal ba\u011flar \u00fcretecektir. Az miktarda Al, y\u00fcksek safl\u0131kta kuvars \u00fcr\u00fcnlerinin kalitesini etkilemeyecektir. IOTA standart kumu, Al element i\u00e7eri\u011fi (12~18)\u00d710-6 gerektirir, ancak optik fiberdeki az miktarda Al, kuvars cam\u0131n \u0131\u015f\u0131k iletimini azaltacakt\u0131r. P elementinin varl\u0131\u011f\u0131, tek kristal silisyumun \u00e7ekilmesini ciddi \u015fekilde etkileyecektir, bu nedenle y\u00fcksek safl\u0131kta kuvars pota, P i\u00e7in y\u00fcksek gereksinimlere sahiptir ve P element i\u00e7eri\u011finin 0,04\u00d710-6’dan az olmas\u0131 gerekir.<\/p>\n","protected":false},"excerpt":{"rendered":"
