“…1 XRD patterns of BaFe12O19/RGO composite However, in this study, there is still an impurity phase, namely hematite (α-Fe2O3), resulting from a small portion of iron sand that did not react completely and unstable calcination temperature during heating in the furnace. This phenomenon was also observed in another research (Rianna et al, 2019), where an impurity phase, namely hematite, was formed.…”

In this study, a composite microwave absorber consist of barium hexaferrite (BaFe12O19) and Reduced Graphene Oxide (RGO) for Ku-band (12-18 GHz) was prosperous blend. Barium hexaferrite to arrange using the sonochemical method and at calcination temperature of 1000°C and a holding time of 1 hour. Subsequently, commercial RGO was composited with barium hexaferrite at a weight percentage of 6% RGO. The synthesized composite was characterized using X-Ray Diffraction (XRD) to analyze the formed phases, Raman Spectroscopy to confirm the presence of RGO in the composite, and Vector Network Analyzer (VNA) to evaluate the microwave absorption performance. The XRD test results show that there is no change in the crystal structure of barium hexaferrite due to the addition of RGO. The VNA test results showed that the addition of RGO could enhance the reflection loss value of barium hexaferrite. The BaFe12O19/RGO compound displayed a reflection loss value of -14.43 dB at a frequence of 16.50 GHz.

“…Di sisi lain, Manikandan et al (2014) juga mempublikasikan berbagai nanopartikel ferit untuk aplikasi fotokatalis, aktivitas antibakteri dan sebagai sensor kelembaban. Spinel ferit dapat diaplikasikan pada biomedis, perangkat elektronik (Anandan et al, 2017), Magnetic Resonance Imaging (MRI) dengan sifat magnet spinel ferit MFe2O4 (M = Fe, Co, Mn) untuk membantu identifikasi penyakit (C.P et al, 2012), dan penyerap gelombang mikro (Sembiring, et al, 2019). Ferit dengan rumus X.Fe2O3 (X= MgO, ZnO, MnO dan CaO) dapat dibuat dalam beberapa metode seperti mechanical alloying, penambahan MgO pada Fe2O3 metode co-presipitasi (Saputra et al, 2020), metode hydrothermal dan sebagainya.…”
