Sintesis Superkonduktor MgB2 Dengan Penambahan Carbon Nanotube Menggunakan Metode Powder In Tube
SINTESIS SUPERKONDUKTOR MgB2 DENGAN PENAMBAHAN
CARBON NANOTUBE MENGGUNAKAN METODE POWDER IN TUBE
ABSTRAK
Dilakukan percobaan sintesis superkonduktor Magnesium Deboride (MgB2)
dengan penambahan Carbon Nanotube (CNT) menggunakan metode Powder in
Tube (PIT). MgB2 adalah superkonduktor yang memilliki temperatur kritis ~39K.
Penambahan CNT sebesar 5, 10 dan 20 wt.% dilakukan untuk mempelajari
pengaruhnya terhadap karakterististik superkonduktivitas material MgB2. Material
ini disintesis dengan metode Powder In Tube (PIT).Bahan baku berupa serbuk
Magnesium (Mg), Boron (B) dan Carbon nanotube (CNT) ditimbang sesuai
perhitungan stoikiometri. Bahan-bahan digerus selama 1 jam menggunakan
mortar kemudian dimasukkan kedalam pipa stainless steel tipe SS304 dan
dilakukan proses pressing dengan tekanan 165 MPa, selanjutnya dilakukan proses
pemanasan (sintering ) menggunakan muffle furnace dengan suhu 850˚C selama
10 jam. Kemudian sampel dikarakterisasi dengan alat XRD, SEM, dan Cryogenic
Magnet. Identifikasi fasa dilihat melalui XRD, terdapat beberapa fasa yang
terbentuk diataranya, MgB2, MgO, Mg dan B. Struktur morfologi yang homogen
dilihat melalui SEM. Dari pengujian Cryogenic Magnet dapat dilihat bahwa
penambahan CNT sebanyak 5wt.%dapat menurunkan temperature kritis (Tc),
sedangkan untuk penambahan CNT sebanyak 10wt.% dan 20wt.% menunjukkan
penurunan sifat superkonduktivitas material MgB2.

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.
