Keywords:
particle size, pressureless sintering, physical properties, sieving mesh
Abstract
Alumina sintered bodies (Al2O3), in the form of pellets, have been made by varying the size of particles. The initial particles were sieved on a 200-270 mesh (53-74 μm). The other sizes were refined using a centrifugal hammer mill and then sieved to obtain particles retained on the 270 mesh (> 54 μm) and the 400 mesh (37-53 μm), and those passed the 400 mesh (<37 μm). Polyvinyl alcohol (PVA) liquid as a binder was added into each of these size variations. The process of mixing alumina with PVA (alcohol as a diluent) was carried out for 2 h in a rotary drum with a ceramic ball in it. The mixture was dried at room temperature for 48 h to remove the alcohol. The mixture was smoothed again using a rotary drum for 2 h with a ceramic ball in it. Green bodies were made by uniaxial pressing method at a pressure of 100 MPa. The sintering process was carried out by preheating at a temperature of 700oC with a holding time of 1 h to eliminate PVA, and then the temperature was increased to 1200oC with a holding time of 2 h. During the sintering, the heating rate was maintained at 5oC/minute. The physical characteristics of the alumina sintered bodies were determined by testing the linear shrinkage, density, and microstructure characterization. Density increased with decreasing particle size, from 2.096 gr/cm3 to 2.140 gr/cm3 with an increase in relative density of 2%. The results showed a change in physical properties along with the reduction in the size of the alumina particles.
