“…At a temperature of 230 0 C, (3.4 %) weight loss has been observed in gure 4(a) which accounts for the removal of impurities. Sukmarani et al [12] also observed a weight loss of (3.8 %) in their nding for a temperature range of (20 to 218 0 C). The decomposition continues in the second zone in gure 2(a) in which a weight loss of (7.9%) occurred.…”

“…Manganese ferrite obtained through these processes is extremely pure, but these processes uses reactants of high cost and complex technological procedures. Sukmarani et al [12] synthesized manganese ferrite from calcinated manganese ore and ferric oxide (Fe 2 O 3 ) through mechanical milling and calcination and found that the formation temperature of Manganes ferrite falls due to the presence of milling process. Naseri et al [13] synthesized manganese ferrite via thermal treatment followed by calcination and found that the sample's super-paramagnetic behaviour gets boosted as the calcination temperature rises.…”

The present study focuses on the synthesis and characterization of manganese ferrite. Manganese ferrite has been synthesized by mixing ferric oxide powder (Fe2O3) with low grade Mn-ore and then sintering it at different temperatures (1000-1200 0C). the method is cheap, simple, and easily controls particle size. It has been established that manganese ferrite phase has been successfully achieved at all the three sintering temperatures however, a higher peak has been noted at sintering temperature of 1200 0C in XRD diffractogram. An increase in particle size with increasing sintering temperature has been reported. Thermal analysis shows a weight gain of ( ) at ( ) which further confirm the phase formation of manganese ferrite. Stretching vibrations were recorded at 1636 cm-1 while some peaks were observed below 1000 cm-1 in FTIR graph which is a common feature of ferrites. Microstructural analysis show small pores at the surface and confirm that the synthesized manganese ferrite nano-particles show best magnetic properties and possess high melting point. A highly synchronous nucleation and growth of the synthesized nanoparticles is also confirmed from TEM analysis. Overall, because of its simpleness and cheapness this method could be used for synthesis of manganese ferrite synthesis.

Synthesis and Characterisation of Mg2+ and Al3+ Co-Doped CoCr2O4 Inorganic Pigments With High Near-Infrared Reflectance

A new class of near-infrared (NIR) reflectance pigments based on Co1−xMgxCr2−yAlyO4 (x = 0–1 and y = 0–2) was synthesised using the Pechini-type sol-gel process. The developed powders were characterised by thermogravimetry and differential scanning calorimetry, X-ray diffraction (XRD), ultraviolet–visible near-infrared diffuse reflectance spectroscopy, and colour Commission Internationale del'Eclairage (CIE) 1976 (L*a*b*) colour scales. The XRD patterns revealed characteristic peaks of the spinel structure with good crystallinity. Substituting Mg2+ for Co2+ ions in the tetrahedral positions and Al3+ for Cr3+ ions in the octahedral positions of CoCr2O4 reduces the cost and changes the colour of the pigment (green to yellow and then blue). Moreover, the synthesised pigments exhibited high NIR solar reflectance in the 780–2,500 nm wavelength range. The thermal and chemical stability of the pigments was also studied. Our findings demonstrate the potential for applying these pigments in cool colourants.

Salah satu sumber daya alam bijih mangan terbesar di Indonesia terdapat di Kab. Sumbawa Besar dan memiliki kadar mangan tinggi. Bijih mangan dapat dimanfaatkan dalam bentuk senyawa manganese ferrite. Sintesis manganese ferrite (MnFe2O3) terdiri dari paduan bijih mangan oksida (MnO2) dan hematit (Fe2O3) yang didapat dari mill scale limbah produksi baja. Kedua partikel tersebut kemudian dipadukan dengan metode mechanical alloying. Bijih mangan terlebih dahulu dikalsinasi pada variasi temperatur 400oC, 500oC, dan 600oC. Proses mechanical alloying paduan bijih mangan dan hematit dengan memvariasikan jumlah bijih mangan 1:1, 1:2, 1:3, 1:4. Selanjutnya campuran partikel tersebut dikalsinasi pada temperatur 1100oC selama 3jam untuk mendapatkan manganese ferrite yang homogen. Karakterisasi XRD awal didapatkan bijih mangan berbentuk pyrochroite (Mn(OH)2) dan setelah kalsinasi pada temperatur 500oC terbentuk pyrolusite (MnO2). Hasil akhir karakterisasi XRD dan XRF menunjukkan bahwa penambahan MnO2 pada Fe2O3 menghasilkan manganese ferrite bixbite (MnFe2O3) dengan intensitas pembentukan 70%. Fasa MnFeO3 dominan pada perbandingan 4:1. Semakin banyak penambahan MnO2 pada Fe2O3, maka semakin banyak fasa manganese ferrite bixbite yang terbentuk.
