Feb 01, 2018 · The present study set out to perform a more comprehensive and detailed study of the crystal structures and properties of Al 2 O 3-Cr 2 O 3 solid solutions with a range of Cr 2 O 3 contents. A simple and rapid method for determining the Cr 2 O 3 content in an Al 2 O 3 -Cr 2 O 3 solid solution, based on X-ray diffraction, is proposed. When naming an ion of a transition metal that has more than one common ionic charge, the numerical value of the charge is indicated by a: Roman numeral following the name In naming a binary molecular compound, the number of atoms of each element present in the molecule is indicated by:
Nov 01, 2019 · The aim of the present study was to introduce Al 2 O 3 –Cr 2 O 3 ceramic system as an armour material by evaluating its performance with static mechanical tests. Cr 2 O 3 was used as an additive to the pure Al 2 O 3 owing to the character of substitutional solid solution formation that would provide increases in mechanical properties.
