ABSTRACT


Two (2) Siruma silica samples, one raw and the other elutriated to obtain a particle size of 2 microns and below (2 >), were analyzed. The raw Siruma silica sample was subjected to X-ray diffraction and particle size distribution analyses, while the 2 > materials was subjected
to X-ray diffraction analysis, TG-DTA, IR, and SEM.


Results of the study shouied that the raw Siruma silica sample is mainly composed of quartz (SiO2) and traces of kaolinite (Al2O3.2SiO2, 2H2O) and sericite (KAI2 (AlSi3O10(OH)2) On the other hand, the elutriated sample ( 2 >) consists of clay minerals, such as, kaolinite and
sericite and traces of very fine particles of quartz.
