1 BAB 5 KESIMPULAN DAN SARAN 5.1 Kesimpulan Dari penelitian yang telah dilakukan dapat disimpulkan hal-hal sebagai berikut: 1. Serbuk magnesium titanat dan larutan padatnya dapat disintesis dengan metode pencampuran basah dengan kemurnian yang tinggi melalui analisis data data Difraksi Sinar-X. 2. Dari hasil uji DTA-TGA, dengan penambahan Zn dapat menurunkan suhu pembentukan fasa MgTiO 3 yang mulai terbentuk pada suhu 280ºC tanpa adanya fasa metastabil. 3. Analisis difraksi sinar-x secara kualitatif maupun kuantitatif menunjukkan bahwa ion Zn 2+ dan Ni 2+ yang mensubstitusi ion Mg 2+ pada MgTiO 3 pada komposisi x = 0,1-0,5 telah terbentuk larutan padat (solid solution). 4. Karakteristik strukturmikro dari ZMT dan NMT mengkonfirmasi bahwa telah terbentuk solid solution sesuai dengan analisis data difraksi sinar-x dan serbuk mengalami aglomerasi. 5.2 Saran 1. Untuk mendapatkan serbuk yang lebih homogen dan tingkat kemurnian yang tinggi, sebaiknya dilakukan sintesis dengan pencampuran larutan lebih lama. 2. Pada penelitian selanjutnya disarankan menggunakan ultrasonic algomerate atau alat Ball Millig untuk mengurangi penggumpalan pada serbuk. 3. Untuk estimasi ukuran kristal, sebaiknya dilakukan penghalusan dengan perangkat lunak Reitica dan MAUD dan dikonfirmasi dengan TEM. 47
