Alumina provides the best cost-benefit ratio among advanced ceramics, featuring high modulus of elasticity, high refractoriness, high hardness, and relatively lower cost. But it has low fracture toughness and low flexural strength, making its ballistic performance lower than SiC and B4C.
The properties of the alumina can be improved by introducing zirconia particles or ceramic fibers, which increase its fracture toughness and flexural strength respectively.
