“…In fact, the introduction of Si, Zr, or Ti particles into the precursor solutions led to the synthesis of SiC, ZrB 2 , or TiB 2 phases along with the B 4 C ceramic. Such an in-situ composite making approach resulted in more uniform size distribution and finer particles [34]. Recently, B 4 C ceramics were synthesized in our laboratory using boric acid and saccharide polymers (glucose, sucrose, and cellulose) at 1500 °C after proper mixing and pyrolysis.…”

Synthesis of boron carbide (B4C) as one of the hardest materials on planet Earth is of particular importance due to its wide range of industrial and engineering applications. For this purpose, boric acid and polymers can be used as the boron and carbon sources, respectively. From the family of saccharides in polymeric materials, glucose has shown the best performance for the synthesis of B4C. In this research, untreated and pretreated (caramelized by heating) glucose precursors were selected and mixed with boric acid for subsequent pyrolysis and synthesis processes. X-ray diffractometry and Fourier transform infrared spectroscopy confirmed that heat-treated glucose is a better carbon precursor for B4C synthesis. In order to evaluate the effect of the amount of boric acid, more than its stoichiometric ratio, additional amounts of boric acid (10-40%) were also examined and the excess amount of 30% was determined as the optimal value.

Composite powders containing titanium diboride and boron carbide have been prepared by sol-gel method at 1450°C using titanium isopropoxide (titanium precursor), boric acid (Boron precursor), sucrose (carbon source), and acetic acid (AcOH) as a solvent. The effect of boron source (trimethyl borate and boric acid) and B 2 O 3 / TiO 2 , C/B 2 O 3 mole ratios of starting materials on the final phases has been studied. The progress of reactions was determined using thermal analysis (TGA-DTA). The resultant powders were characterized by X-ray diffraction (XRD) analysis and field-emission scanning electron microscope (FESEM). XRD patterns confirmed the formation of TiB 2 , B 4 C, and TiC phases after heat treatment at 1450°C at mole ratio of B 2 O 3 /TiO 2 = 4.5, C/B 2 O 3 = 2.4. With increasing the content of boron oxide, the unwanted phases such as TiC and C were reduced. TiB 2 and B 4 C composite powders (~5 µm diameter) containing residual carbon (<4 wt%) were synthesized using the mole ratio of B 2 O 3 /TiO 2 = 10 and C/B 2 O 3 = 1.9 at low temperature of 1450°C.
