Mechanochemical preparation of a modified NiAl₂O₄structure

Abstract

Mechanochemical synthesis routes offer a sustainable, simple method of preparing materials. In this work, NiAl2O4 was synthesised by a mechanically activated method using a high-energy planetary mill and a calcination...

Study of the effect of synthesis temperature and thermal aging on structural, dielectric properties and phase composition in NiO/NiAl2O4 composite ceramics

“…The synthesis method also influences the physicochemical properties of aluminates. Different methods for obtaining aluminates are known: sol-gel synthesis [19,20] combustion method [21], chemical precipitation [22], and solid-state sintering [23,24]. It is important to note that the bottom-up method, which assumes mixing of components at the atomic level and the best homogeneity of distribution, is not always advantageous [25].…”
