Description
Summary:Synthesis of the Al 2 O 3 -B 4 C ceramic was carried out in this study via mechanochemical method. A highest value of 64.72 m 2 /g was obtained at the end of milling for 6 h during the BET analyses carried out for determining the surface area of synthesis powders. The bond structures between Al–O and B–C were determined in FT-IR analysis in accordance with the data acquired from relevant literature. Peaks for only the Al 2 O 3 and B 4 C phases were determined by XRD analysis before and after the leaching process especially after an 8 h milling. The Al 2 O 3 -B 4 C composite powder obtained after milling under optimum milling conditions for 8 h was shaped into pellet with and without the addition of 2% by weight binder (paraffin) in a uniaxial press and cold isostatic press. The Al 2 O 3 -B 4 C composite obtained has a relative density value of 86% after sintering in the Ar atmospheric tube furnace at 1550 °C.
