Abstract
In this study, alumina-iron composites have been prepared by slip casting in order to provide gradient iron in alumina. 5 wt.% of iron was used under the magnetic fields by the magnitude of 0.8 and 0.08T. Two dispersants were examined as the dispersing agent using 70, 75 and 80 wt.% of solid loading in slips. Samples were sintered in a microwave oven at the temperature of 1350˚C and 1450˚C for 30 minutes, at 1500˚C for 1 minute, and in a conventional tube oven at the temperature of 1485˚C for 2 hours using argon gas. The apparent and optical microscope pictures of green and sintered samples revealed that using PCN and 70 wt.% of solid loading under the mild magnetic field results in the best sample regard as density (3.7 g/cm3 ), strength (82.7 MPa) and iron gradient.
