In mineralogy, tenacity is a mineral's behavior when deformed or broken. Common terms. Brittleness. The mineral breaks or powders easily. Most ionic-bonded minerals ...
A few minerals such as calcite and kyanite have a hardness that depends significantly on direction. [9]: 254–255 Hardness can also be measured on an absolute scale using a sclerometer; compared to the absolute scale, the Mohs scale is nonlinear. [8]: 52 Tenacity refers to the way a mineral behaves, when it is broken, crushed, bent or torn.
Tenacity may refer to: Tenacity (psychology), having persistence in purpose; Tenacity (mineralogy) a mineral's resistance to breaking or deformation; Tenacity (herbicide), a brand name for a selective herbicide; Tenacity (textile strength) Tenacity (audio editor), an Audacity fork; Tenacity (non-profit), an organization founded by Ned Eames

Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium, and chromium. [3] [4] It is a rock-forming mineral.It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
Sectility can be used to distinguish minerals of similar appearance, and is a form of tenacity. [2] For example, gold is sectile but pyrite ("fool's gold") is not. Sectility in metals is a result of metallic bonding , where valence (bonding) electrons are delocalized and can flow freely between atoms, rather than being shared between specific ...
