Description

Penelitian mengenai energi alternatif berbasis material perovskite saat ini tengah menjadi pusat perhatian karena berpeluang sebagai aplikasi ramah lingkungan yang murah. Senyawa LaCoO3 (lanthanum cobaltite) termasuk salah satu material perovskite yang memiliki peluang berbagai aplikasi seperti katalis, membran pemisahan oksigen, katoda oksida padat bahan bakar dan sensor O2. Pada penelitian ini akan membahas mengenai sintesis LaCoO3 menggunakan teknik reaksi padatan dengan variasi suhu penyinteran pada 900, 1000 dan 1100 oC. Sampel penyinteran yaitu berupa pellet dengan diamater 12 mm. Pola difraksi sinar-X menunjukkan pembentukan polikristal LaCoO3 sudah terjadi pada T = 900 oC dengan sudut 2θ = 23,20 ; 32,90 ; 32,96 ; 40,62 ; 47,50 ; 58,98 ; 59,70 ; 68,96 ; 69,96 ; 78,78 ; 79,48. Untuk suhu 1000 dan 1100oC membentuk pola difraksi yang identik dengan suhu 900oC, namun memiliki intensitas yang fluktuatif. Keadaan tersebut disebabkan oleh peristiwa distorsi kristal LaCoO3 seiring peningkatan temperatur penyinteran.
