Abstract

Kajian tentang karakteristik kaolin lokal asal Tatakan, Tapin, KalimantanSelatan setelah proses kalsinasi pada temperatur 800°C selama 3 jam telah dilakukanuntuk mengetahui perubahan struktur kaolin. Sampel kaolin sebelum dan setelahproses kalsinasi dianalisis menggunakan spektroskopi infra merah (FTIR), difraksisinar X (XRD) dan scanning electron microscopy (SEM). Hasil analisis menggunakanFTIR menunjukkan terjadinya kerusakan struktur dari kaolin akibat proses kalsinasiyang ditandai dengan hilangnya puncak serapan khas dari kaolin. Berdasarkan dataXRD dan analisis morfologi menggunakan SEM, proses kalsinasi menyebabkanperubahan struktur kaolin dari pseudoheksagonal berlapis menjadi fasa amorf.

Abstract

Synthesis of g-Al2O3 from Tatakan, South Kalimantan kaolin using simple methods: metakaolinization, dealumination, precipitation process using polyethylene glycol (PEG-6000) as a structure directing agent, calcination steps, and characterization of its products have been presented. The purified kaolin was metakaolinized and dealuminated to get amorphous aluminum hydroxide.  After that, the sample was precipitated using the various concentration of PEG and NH4OH as the precipitating agent. Calcination process was carried out at calcined at a temperature of 700°C for 3 hours. Based on the FTIR spectra and X-ray diffraction of the g-Al2O3 obtained was similar to that of commercial g-Al2O3. The highest crystallinity of g-Al2O3 was formed when using twice of critical micelle concentration of PEG (10-3 mol/L).  This simple process is an industrially practicable substitute to the Bayer process
