Abstract

Telah dilakukan penelitian tentang karakterisasi bentuk partikel SiC yang dilapisi spinel (MgAl2O4) dengan menggunakan metode electroless platting. Penelitian ini bertujuan untuk mengetahui pembentukkan spinel pada permukaan partikel SiC melalui tahapan awal pembentukkan lapisan SiO2 serta mengidentifikasi parameter bentuk partikel. Variasi yang digunakan dalam penelitian ini adalah waktu penahanan 2, 6, 10 dan 14 jam pada suhu pemanasan 12000C. Karakterisasi yang digunakan untuk menganalisis material SiC yang telah dioksidasi maupun material SiC yang telah dilapisi dengan spinel yaitu XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy) dan EDS (Energy Dispersive Spectroscopy). Hasil analisis menunjukkan bahwa seiring peningkatan holding time, maka semakin tebal lapisan SiO2. Spinel yang terbentuk adalah semakin homogen di permukaan partikel SiC berdasarkan spektrum EDS. Pelapisan SiO2 dan spinel akan mempengaruhi beberapa parameter bentuk partikel, yaitu menurunkan nilai Bulkines Factor (Bf), menurunkan nilai Shape Factor (Ks) dan meningkatkan nilai perimetri. ================================================================================================================ A research about characterization of particle shape SiC coated with spinel (MgAl2O4) using electroless platting has been completed. The purposes of the research are determining the spinel formation on the surface of SiC particles through the formation of the SiO2 layer and identifying the parameters of particle shape. Variations that used in this research was holding time 2, 6, 10 and 14 hours in heating temperature 12000C. Characterization were done using XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy) and EDS (Energy Dispersive Spectroscopy). The results showed that SiO2 layer increased as the increasing of holding time. Spinel has formed homogeneously on the surface of SiC particles based on EDS spectrum. The coating of SiO2 and spinel would affect the particle shape parameters, such as decreasing the value of Bulkines Factor (Bf), decreasing the value of Shape Factor (Ks) and increasing the value of perimetry.
