Effect of ceramic additives on mechanical properties of alumina matrix composites

摘要

Alumina ceramics have excellent mechanical properties for technical application. The lower purity alumina compacting powders are used in wide range of engineering ceramic industry. These powders contain low amounts of additional materials (SiO_2, CaO, MgO). In this article, the authors present the achievement of some mechanical experiments using variable ceramic additives for preparing test specimens. The aim of this work to enhance the mechanical performance of the lower purity alumina (94%) develops a ceramic composite system. Further aim of this work to attempt to reach the values of mechanical properties of high purity alumina products. Zirconia was used in variable amounts as restorative material.
