Pengaruh Ukuran Bola Milling Terhadap Sifat Kristalinitas Dan Distribusi Ukuran Nanopartikel Magnetik Disintesis Dari Pasir Pantai Sungai Suci Bengkulu

---

Research on the crystalline size and particle size distribution of magnetic
nanoparticles of beach sand Sungai Suci Bengkulu synthesized using 2-stage ball
milling method has been done. The samples were characterized using X-Ray
Diffractometer (XRD) and Particle Size Analyzer (PSA). Magnetic induction
measurement on ball milling products has been carried out using Pasco magnetic
probes. Iron oxide and non-iron oxide particles were separated using Neodymium
Iron Boron (NdFeB) magnets. The Product of NdFeB was milled for 60 hours
using milling ball combination of 0.5, 0.7 and 1.5 cm in diameter. This product
was divided into three parts called BMIA, BMIB and BMIC and then milled
separately for 40 hours using milling balls with diameter of 0.5, 0.7 and 1.5 cm,
respectively. The products of this ball milling are called BMIIA, BMIIB and
BMIIC. The results show that magnetic susceptibility of BM II products increases
with increasing milling ball size that is 9215.48x10-5, 10097.64x10-5 and
11056.87x10-5 for milling ball size of 0.5, 0.7 and 1.5 cm, respectively. Magnetic
phases of BM II products reveals cubic crystal systems on magnetite (Fe3O4) and
monoclinic on hematite (Fe2O3). The crystal size was calculated using Scherrer
formula for the highest peak of diffraction patterns of XRD that is 26.794 nm,
28.740 nm, 27.645 nm for BMIIA, BMIIB and BMIIC, respectively. The average
crystal size increases from 30.4315 nm, 34.1085 nm 35.0630 nm with increasing
milling ball diameter. The particle size distributions of the samples were
determined using the Particle Size Analyzer (PSA). The results show that the
distribution of particle size at a percentage of 10% is 1.45 μm, 0.40 μm and 1.30
μm for BMI, BMIIA and BMIIC, respectively.
