β-tin, also called white tin, is the allotrope (structural form) of elemental tin that is stable at and above room temperature. It is metallic and malleable, and has body-centered tetragonal crystal structure. α-tin, or gray tin, is the nonmetallic form.

Jun 5, 2023 · Tin has two primary allotropes: α-tin (grey) and β-tin (white); beta-tin is more stable, silvery-white in appearance, and malleable at room temperature. However, alpha-tin is more stable at lower temperatures and has a diamond-cubic structure.

Tin is found in two allotropes: alpha-tin and beta-tin. Alpha-tin is a brittle, dull, powdery, semimetallic form of tin. It is made when very pure tin is cooled. Beta-tin is the normal shiny, soft, conductive, metallic form. It is made at higher temperatures. The decay of tin by turning from beta-tin to alpha-tin is called tin pest. Alpha-tin ...

Beta tin is the most commonly found allotrope of tin, and gamma tin only exists at very high temperatures. Tin, although it is found in Group 14 of the periodic table, is consistent with the trend found in Group 13, where the lower oxidation state is favored farther down a group.

Comprising a small fraction of the earth’s crust, only about .001%, tin is obtained and extracted from the mineral cassiterite. There are two allotropes or forms of tin that occur at room temperature; one of them being gray (alpha) tin and the other white (beta) tin.

Tin exists in two modifications: β-tin (the metallic form, or white tin) is stable at room temperature and above room temperature is malleable. In contrast, α-tin (nonmetallic form, or gray tin) is stable below 13.2°C, is brittle with no metallic properties.

Tin, tin alloys and intermetallic tin compounds play a key role in many technologies and high-tech applications. Many of these intermetallics find application in daily life such as pewterware,...

Nov 24, 2022 · The most famous material with the diamond tetragonal crystal structure is β-Sn, or white tin. In fact, the diamond tetragonal crystal structure is usually just called the white tin crystal structure. I prefer this name, however, because it more clearly identifies the atom positions.
