Abstract (2. Language): 
The carbothermal reduction of mechanically activated chromite with metallurgical coke under an argon atmosphere was investigated at temperatures between 1100 and 1400°C and the effects of the mechanical activation on chromite structure were analyzed by x-ray diffraction (XRD) and scanning electron microscopy (SEM). An increase in specific surface area resulted in more contact points. The activation procedure led to amorphization and structural disordering in chromite and accelerated the degree of reduction and metalization in the mixture of chromite and metallurgical coke. Carbothermal reduction products were analzed by using scanning electron microscopy (SEM/EDS).

Mekanik aktive edilmiş kromitin argon atmosferi altında metalurjik kokla karbotermal redüksiyonu 1100 – 1400°C sıcaklık aralığında incelenmiş ve kromit yapısına mekanik aktivasyonun etkisi X-ışını difraksiyonu (XRD) ve taramalı elektron mikroskobisi (SEM) ile analiz edilmiştir. Yüzey alanındaki artış daha fazla temas noktasının oluşmasına neden olmuştur. Aktivasyon prosedürü kromitte amorflaşma ve yapısal düzensizliğe neden olmuş ve kromit ile metalurjik kok karışımında redüksiyon derecesini ve metalleşmeyi hızlandırmıştır. Karbotermal redüksiyon ürünleri taramalı elektron mikroskobisi (SEM/EDS) ile analiz edilmiştir.
