Abstract

In this study, synthesis and characterization of high temperature Yb2O3–ZrO2 insulation coatings on Ag substrate were investigated for magnet technologies. The produced powders and coatings were characterized by using DTA-TG, FTIR, XRD, SEM-EDS, refractometer, spectrophotometer and empendance machines. The DTA/TG result indicates three-stage decomposition for amorphous Yb2O3–ZrO2 composites. FTIR studies revealed that heat treated powders indicate several absoption bands corresponding to O-H, carboxyl and oxide groups. Though ZrO2 phase present in the structures with high intensity, Yb3O2 phase possessess low intensity peak. A regular surface morphology generally forms once YbO3 content increase in ZrO2 from 0 mole % to 12 mole %. The refractive indexes of Yb2O3–ZrO2 coatings were found to be in the range of 1.3539 and 1.3655. The film thicknesses of all coatings generally increased from 0.50 µm to 1.20 µm according to number of dipping. Optical band gap values of Yb2O3–ZrO2 coatings are approximately 3,014 eV. Empedance values of ZrO2 and Yb2O3ZrO2 coatings were measured as 2.52 ohms and 2.51 ohms, respectively

Özet

Bu çalışmada, mıknatıs teknolojileri için Ag altlık üzerinde yüksek sıcaklık Yb2O3–ZrO2 yalıtkan kaplamalaraın sentezlenmesi ve karakterizasyonu incelenmiştir. Üretilen tozlar ve kaplamalar DTA-TG, FTIR, XRD, SEM-EDS, refraktometre, spektrofotometre ve empedans cihazları kullanılarak karakterize edilmiştir. DTA-TG sonucu amorf Yb2O3–ZrO2 kompoziti üç kademeli bozunma göstermiştir. FTIR çalışmaları ısıl işlem yapılmış tozların O-H, karboksil ve oksit gruplara tekabül eden çeşitli absorbsiyon bandlarını içerdiğini açıklamıştır. Kaplama yapısında ZrO2 fazı yüksek şiddette olmasına rağmen, Yb3O2 fazı düşük şiddete sahiptir. ZrO2‘daki Yb2O3 içeriği % 0 molden % 12 mole artırıldığında, genellikle düzenli yüzey morfolojisi oluşmuştur. Yb2O3–ZrO2 kaplamaların refraktif indeksi 1.3539 ve 1.3655 aralığında bulunmuştur. Tüm kaplamaların kalınlıkları daldırma sayılarına göre 0.50 µm’den 1.20 µm’e değişmiştir. Yb2O3–ZrO2 kaplamaların optik enerji aralığı yaklaşık olarak 3,014 eV’dir. ZrO2 ve Yb2O3ZrO kaplamaların empedans değerleri sırasıyla 2.52 ohm ve 2.51 ohm olarak ölçülmüştür. © Afyon Kocatepe Üniversitesi
