Abstract
Pengaplikasian superkonduktor ini untuk kebaharuan teknologi material yang memiliki karakteristik listrik yang lebih efesien dan mampu diaplikasikan dialat Kesehatan maupun motor listrik. Tujuan pengujian ini mengidentifikasi tekstur kristalografi kawat superkonduktor Bi72Sr72Cu72Ca36O296 dan Pb1Bi1O2.68 dengan data XRD dan peaks-2θ, mengobservasi struktur mikro dan elemental mapping kawat superkonduktor dengan metode scanning electon microscope (SEM) dan mengetahui sifat keras dari kawat BPSCCO hasil sintesis dan pabrikasi dengan analisis mikro Vickers dan kuantitatif. Hasil rata-rata pengujian kekerasan kawat superkonduktor BPSCCO sebesar 486,4 HV. Karakeristik sifat keras kawat superkonduktor sesuai aplikasi yag dibutuhkan. Senyawa Bi72Sr72Cu72Ca36O29 memiliki 2θ = 29.3670 dengan intensitas 138,40 count second (cts) dan fasa Pb1Bi1O2.68 optimum pada 2θ = 29.3670 dengan intensitas 28,96 cts. Dari hasil pengujian XRD Senyawa Bi72Sr72Cu72Ca36O29 merupakan struktur monoklinik dengan parameter kisi kisi a = 37,7540 Å, kisi b = 5,4110 Å, dan kisi c = 41,0700 Å dan senyawa Pb1Bi1O2.68 merupakan stuktur orthorhombic dengan parameter kisi a = 5,4110 Å, kisi b = 30,8730 Å, dan kisi c = 5,4160 Å. Bentuk kristalin ini sangat merata menyebabkan butiran semakin rapat dan homogen. Unsur Bi,Sr dan Pb tersebar di bagian grain-grain putih, sedangkan unsur Ca, Cu dan O tersebar merata di permukaan sampel.
The application of this superconductor for the newness of material technology that has more efficient electrical characteristics and can be applied in medical devices and electric motors. The purpose of this test is to identify the crystallography texture of Bi72Sr72Cu72Cu72Ca36O296 and Pb1Bi1O2.68 with XRD and peaks2θ data, observe microstructures and elemental mapping of superconducting wires with the scanning electon microscope (SEM) method and know the hard properties of bpscco wire synthesis and milling by micro Vickers and quantitative analysis. The average result of bpscco superconducting wire hardness test was 486.4 HV. Karakeristic hard properties of superconducting wires according to application are needed. Compound Bi72Sr72Cu72Ca36O29 has 2θ = 29.3670 with an intensity of 138.40 count second (cts) and phase Pb1Bi1O2.68 optimum at 2θ = 29.3670 with an intensity of 28.96 cts. From the test results of XRD Compound Bi72Sr72Cu72Ca36O29 is a monoclinic structure with lattice parameters a = 37.7540 Å, lattice b = 5.4110 Å, and lattice c = 41.0700 Å and compounds Pb1Bi1O2.68 are orthorhombic structures with lattice parameters a = 5.4110 Å, lattice b = 30.8730 Å, and lattice c = 5.4160 Å. This crystalline form is very evenly distributed causing the granules to get tighter and homogeneous. Elements Bi, Sr and Pb are scattered in the white grains, while the elements Ca, Cu and O are evenly distributed on the surface of the sample.
