SINTESIS CERAMIC METAL (CERMET) Ni-YSZ DARI ZIRKON LOKAL SEBAGAI MATERIAL ANODA SOLID OXIDE FUEL CELL

Karima Apriany, Fitria Rahmawati

Abstract

Guna meningkatkan nilai ekonomi dari konsentrat zirkon lokal dari Pulau Bangka, Cermet Ni-YSZ disintesis dari zirkonia yang sebelumnya telah disintesis dari konsentrat zirkon lokal. Cermet Ni-YSZ disintesis dengan menggunakan metode solid state reaction. Analisis XRD yang dilengkapi dengan refinement Le Bail telah dilakukan untuk menganalisis struktur kristal dan parameter sel dari material. YSZ dipreparasi dengan melakukan doping 8% mol yttrium oxide kedalam zirkonia dan kemudian disinter pada suhu 1250 oC selama 3 jam. ada penambahan doping 8% mol yttria memungkikan transfomasi fasa dari zirkonia dari tetragonal menjadi struktur kubik. Sementara itu, cermet Ni-YSZ memiliki fasa kristalin, Ni dengan struktur kubik dan YSZ dengan struktur kubik. analisis sem dari material-material tesebut  menunjukan bahwa adanya penambahan Ni kedalam YSZ memungkinan morfologi menjadi lebih kasar dengan ukuran butir besar yang disebabkan adanya agglomerasi Ni terhadap YSZ. cermet Ni-YSZ memiliki konduktivitas tertinggi pada komposisi Ni:YSZ 20:80.
