Hardness and deformation properties of solids at very high ...

This paper describes an experimental study of the deformation and strength properties of refractory solids at temperatures up to 2000 °C. It is difficult to make direct stress-strain measurements at elevated temperatures on small specimens of these materials, and consequently the strength property measured was in dentation hardness.

Properties of Matter Hardness and SoftnessTransparency ...

These properties help us to recognise them. We touch a material, see its color, smell it and thereby recognise it. The features which help us to recognise a particular material are called properties of the material. 1. Hardness and softness: Some materials are hard and some are soft. Stone is hard while clay and plastic are soft.

12.5: The Structure of Ionic Solids - Chemistry LibreTexts

2020-8-14  Some Properties of Ionic Solids. As noted above, ionic solids are generally hard and brittle. Both of these properties reflect the strength of the coulombic force. Hardness measures resistance to deformation. Because the ions are tightly bound to their oppositely-charged neighbors and, a mechanical force exerted on one part of the solid is ...

2020-8-14  Ionic Solids. Ionic solids, such as sodium chloride and nickel oxide, are composed of positive and negative ions that are held together by electrostatic attractions, which can be quite strong (Figure \(\PageIndex{3}\)).Many ionic crystals also have high melting points. This is due to the very strong attractions between the ions—in ionic compounds, the attractions between full charges are ...
