Analisa Kadar Free-AlF3 dan CaF2 dalam Larutan Na3AlF6 pada Tungku Reduksi Secara X-Ray Difraksi di PT INALUM Kuala Tanjung

Abstract

Analysis content of f-AlF3 and CaF2 in electrolite solution (Cryolit – Alumina) had been done to reduction fireplace in PT INALUM as X-Ray Difraction. With level standart that has been stablet by the company for reduction fireplace in order can operate well. The content has been stablet by the company for f-AlF3 that it 8 – 11 % by range ± 1 % and CaF2 that it 5 % by range ± 1 %. From analysis product as XRD obtained data on average the content of f-AlF3 that it 8.6 % and caF2 is 4.6 %. So content of f-AlF3 and CaF2 in electrolitesolution to reduction fireplace still fulfill standart normal operate for electrolisa auminium process.
