abstract = "A carbothermal reduction and nitridation process (CRN) was employed to prepare Si3N4-SiC nanocomposite powder [1-4]. Diatomaceous earth from Serbian deposite was used as Si precursor in the synthesis of nanocomposite powder by mixing with commercial sugar as reduscing agent. Purified diatomaceous earth with pre-determined C/SiO2 ratio of 5 yuilded Si3N4-SiC nanocomposite powder. The XRD (Rietveld analysis) was employed to evaluate Si3N4/SiC ratio of the obtained powder after CRN. Also IR and SEM analysis were used to determine morphology and chemical composistion. The results show that the optimally temperature was 1450 degrees C, which is wery low, compared to the classical synthesis process.",
