Boron carbide powder was synthesized by sol-gel polycondensation of boric acid with citric acid. The starting materials of Serbian origin were dissolved in water and mixed homogeneously until a precomposite gel was formed, which was converted into cryogels after freeze-drying. Pyrolysing and subsequent heat treatment of these cryogels resulted in boron carbide materials.
