Abstract

PHASE TRANSITION IN Fe3O4/Fe2O3 NANOCOMPOSITES BY SINTERING PROCESS. Fe3O4 powders have been successfully produced by using coprecipitation method. The characterization using X-Ray Diffraction method resulted in the size of Fe3O4 powders of 9.1 ± 0.3 nm. Samples were then formed into pellete and powders. Heat treatment at temperature 600 oC of powder samples for 1 hour and 2 hours give maghemite and hematite phases, but heat treatment at temperature 700-800 oC for 1 hour, 2 hours and 3 hours give only one phase namely hematite. Heat treatment at temperature 600 oC, 700 oC and 800 oC of pelletes for 1 hour, 2 hours and 3 hours give also only one phase which is hematite. Quantitative analysis using MAUD program resulted in Fe3O4/Fe2O3 composites with changing crystal size at increasing temperature.

Abstract

PREPARASI NANOPARTIKEL Fe3O4 DARI PASIR BESI DAN PELAPISANNYA PADA LOGAM NON MAGNETIK. Telah berhasil disintesis partikel Fe3O4 dengan metode ko-presipitasi dengan dan tanpa penggunakan poli-etilen-glikon (PEG)-400 sebagai template dalam pelarut HCl dan pengendap NH4OH. Hasil sintesis tanpa templatemenunjukkan ukuran kristal dari partikel Fe3O4 < 10 nm yang berbentuk sferis, sedangkan penggunaan PEG-400 meningkatkan ukuran kristal hingga > 10 nm. Proses pelapisan partikel dilakukan dengan cara spin-coating pada permukaan aluminium setelah sebelumnya partikel dilarutkan di dalam surfaktan tetra-metil-amonium-hidroksida (TMAH). Dipelajari hasil pelapisan dengan menggunakan foto SEM dan AFM/MFM, yang mencakup aspek-aspek homogenitas penyebaran partikel dan morfologinya serta faktor korosi oleh surfaktan TMAH.
