Abstract


Penelitian tentang karakteristik bentuk partikel SiC yang dilapisi dengan (MgAl2O4) berdasarkan variabel konsentrasi ion logam telah dilakukan. Dalam penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi ion logam pada permukaan SiC dan mengetahui bentuk permukaan SiC yang sudah terlapisi dengan spinel. Dalam penelitian ini menggunakan metode kopresipitasi dan menggunakan perbedaan konsentrasi Mg 0.6 gram, 1.2 gram, dan 3 gram. Karakterisasi dan identifikasi partikel SiC menggunakan XRD, SEM, dan EDX . Berdasarkan hasil penelitian bahwa pertambahan konsentrasi meningkatkan kekasaran permukaan dan luas kontak permukaan tetapi tidak mempengaruhi kesimetrian dari partikel SiC sehingga wetabbility partikel SiC ketika dipergunakan pada komposit akan meningkat.
