Synthesis of an Al‐ZrO₂ composite by infiltration of Zr‐chelates into an Al matrix

Aluminium‐based matrix composites were prepared by infiltration with an ammoniacal zirconium chelate within an Al matrix synthesized via aluminium powder compactation. Based on differential thermal analysis, Fourier transformed infrared, X‐ray diffraction, and scanning electron microscopy, we confirm the reaction sequence to obtain the tetramer, the phase transformation sequence within the Al matrix, and the development of phases that leads to the synthesis of the Al‐ZrO₂ composite.
