Magnesium aluminate whiskers were synthesized by an oxidation—reduction reaction between MgO, C, and Al in a CO and CO 2 atmosphere. The oxygen partial pressure suitable for MgAl 2 O 4 whisker growth ranged from 10 −12.1 to 10 −11.5 MPa. The average whisker diameter and length formed at 1500°C for 8 h were ∼3.1 μm and ∼4 mm, respectively. The whiskers grew in the [111] direction.
