Investigation of the Effect of Addition of Zirconia and Talc on Sintering Behavior and Mechanical Properties of B4C
In this paper the effect of addition of zirconia and talc as sintering aid has been investigated on mechanical properties and sintering behavior of boron carbide. Different amounts of these materials mainly 0-30 wt% were added to the starting powder and sintered at two different temperatures, 2050°C and 2150°C. Examination of the samples revealed that the both materials improve sintering behavior and mechanical properties of boron carbide. However, talc which is more abundant compare to zirconia could be a proper substituent for zirconia in this system.
