What is Hume Rothery ratio?
For interstitial solid solutions, the Hume-Rothery Rules are: Solute atoms should have radius no larger than 15% of the radius of solvent atoms. The solute and solvent should have similar electronegativity. The greater the difference in valence between solute and solvent atoms, the lower the solubility.Click to see full answer.

For interstitial solid solutions, the Hume-Rothery Rules are: Solute atoms should have radius no larger than 15% of the radius of solvent atoms. The solute and solvent should have similar electronegativity. The greater the difference in valence between solute and solvent atoms, the lower the solubility.Click to see full answer. Subsequently, one may also ask, why are Hume Rothery’s rules followed?The Hume-Rothery rules state that two elements must be very similar to each other in order to form a solid solution, because any dissimilarities can cause separation like in the case of oil and water. The two elements must therefore meet all of the following conditions in order to mix and form a solid solution.Also, what are the four Hume Rothery rules for the solid solubility of one element in another? Chapter 8, Solution 8 The four Hum – Rothery rules for the solid solubility of one element in another are: 1. The crystal structure of each element of the solid solution must be the same. 2. The size of the atoms of each of the two elements must not differ by more than fifteen percent. Beside above, do the Hume Rothery rules apply to ceramics? Hume-Rothery rules can be applied to the ceramic system. For instance, the ceramic system of MgO and NiO satisfy these set of rules and thus are soluble in each other. The atomic radii of both the compounds, MgO and NiO are similar.What is solid solution and its types?Solid solution is a phase, where two or more elements are completely soluble in each other. Depending on the ratio of the solvent (matrix) metal atom size and solute element atom size, two types of solid solutions may be formed: substitution or interstitial.
