Effect of TiSi2 addition on densification of Cerium hexaboride
Abstract
<p>This paper reports the result of investigation carried out on the synthesis and densification of Cerium hexaboride. CeB<sub>6</sub> was synthesized by boron carbide reduction of CeO<sub>2</sub> in presence of carbon. Effect of temperature on product quality was investigated. Pure CeB<sub>6</sub> powder was obtained at 1600 °C, in vacuum. It was found that CeBO<sub>3</sub> is formed as an intermediate phase during CeB<sub>6</sub> synthesis. Spark plasma sintering of CeB<sub>6</sub> powder at 1900 °C and 70 MPa resulted in a density of only 93.4% of theoretical value. Addition of 5% TiSi<sub>2</sub> resulted in 97.4% of theoretical density at the lower temperature of 1650 °C. Hardness and fracture toughness of the composite was measured as 21.08 GPa and 3.8 MPa·m<sup>1/2</sup> respectively. Fractured surface of the composite reveals the mode of fracture to be transgranular. SEM and EDS analysis indicate the presence of TiSi<sub>2</sub> in CeB<sub>6</sub> matrix.</p>
