Abstract
Alumina powders containing varying ratios of B4C were mixed in a V-type mixer for 30 min with 35 cycle/min to obtain a homogeneous mixture. Six different chemical compositions were prepared and sintered at 1600 °C for 20 min using an Ultra-High-Frequency Induction Heated System. The samples were cooled by air. The density, surface roughness, hardness and microstructure of samples were investigated. The results showed that when the amount of B4C increased, the values of hardness increased and the values of surface roughness decreased.

Key words
alumina, boron carbide, sintering, induction, composite
