Sintesis Superkonduktor Mgb2 dengan Penambahan Carbon Nanotube Menggunakan Metode Powder In Tube

Abstract

The synthesis of Magnesium deboride (MgB2) superconductor with the addition of Carbon Nano Tube (CNT) using Powder in Tube (PIT) method has been done. MgB2 superconductors has critical temperature ~ 39K. The addition of CNT 5, 10 and 20 wt.% conducted to study its effect on characteristic against superconductivity in MgB2material.This material is synthesized by the method Powder In Tube (PIT). Raw materials floured Magnesium (Mg), boron (B) and Carbon Nanotubes (CNT) were weighted based on the calculation stoiciometry. The materials is milled for 1 hour using mortar and then inserted into the type of SS304 stainless steel pipe and do a pressing process with a pressure of 165 MPa, furthermore do heating process (sintering) using a muffle furnace at a temperature of 850˚C for 10 hours. Then the samples were characterized by means of XRD, SEM, and Cryogenic Magnet . Phases identification seen by XRD, there are several phases that form such as, MgB2, MgO, Mg and B. The structure of homogeneous morphology seen through SEM. Based on testing of Cryogenic Magnet can be seen that the addition of CNT as 5wt.% Can lower critical temperature (Tc), where as for the addition of CNTs as much as 10wt.% And 20wt.% Showed a decrease in the material properties of superconductivity in MgB2.
