Nonmetallic Grey (Alpha) Tin Allotrope, 5 Grams in Glass Vial - Collection, Display, Education
Each borosilicate glass vial contains 5 gram of pure nonmetallic grey (alpha) allotrope tin granules Perfect for element collections, displays and for educational purposes.
Grey tin (or alpha tin) is a nonmetallic allotrope of tin, which is typically found in the form of metallic white or beta-tin. It forms very slowly when metallic tin is brought below about 13.2 degrees Celsius. This allotropic change has caused problems throughout history, especially in cold climates. Grey tin is brittle and has a lower density than metallic tin, which causes it to crumble as it forms and expands. It has very few uses in any industry, but is a valuable addition to any element collection.
