Abstract

Penentuan kondisi optimum meliputi waktu milling Nb dan Sn dengan HEM (High Energy Milling), perbandingan jumlah Nb dan Sn, waktu dan temperatur pemanasan campuran Nb dan Sn. Pengamatan karakterisasi Nb3Sn yang terbentuk dilakukan dengan  menggunakan DTA (Differential Thermal Analyzer), XRD ( X-Ray Diffraction), SEM (Scanning   Electron Microscope) dan EDS (Enegy Dispersive x-ray Spectroscopy). Analisis dengan menggunakan SEM dan XRD menunjukkan waktu minimum yang diperlukan untuk milling campuran Nb dan Sn adalah 3 jam, sedangkan hasil dari analisis DTA menunjukkan pembentukan Nb3Sn terjadi pada temperatur sekitar 700 °C. Analisis XRD terhadap campuran Nb dan Sn menunjukkan bahwa makin lama waktu pemanasan maka fasa intermetalik Nb3Sn yang terbentuk akan semakin banyak. Abstract Determination of optimum conditions include milling time of Nb and Sn with HEM, ratio of Nb and Sn, heating time and heating temperature of mixed Nb and Sn. Characterization of Nb3Sn produced from the process was performed using DTA, XRD, SEM and EDS. The results of SEM and XRD analysis showed the minimum time needed for milling Nb and Sn are 3 hours, and the result of DTA analysis showed the intermetalic phase of Nb3Sn was occured at the temparetuir around 700 °C. The result of XRD analysis for mixed Nb and Sn showed that by the increasing of heating time will produced more intermetalic phase of Nb3Sn.
