Crystal structure "white tin" respectively. Two more allotropes, γ and σ, exist at temperatures above 161 °C and pressures above several GPa. White tin is metallic, and is the stable crystalline form at or above room temperature. Below 13.2 °C, tin exists in the gray form, which has a diamond cubic crystal structure, similar to diamond, silicon or germanium. Gray tin has no metallic properties at all, is a dull gray powdery material, and has few uses, other than a few specialized semiconductor applications. Although the α–β transformation temperature of tin is nominally 13.2 °C, impurities (e.g. Al, Zn, etc.) lower the
Telugu wedding ceremony The ceremony is held under a "Kaḷyāṇa Maṇḍapaṃ" or wedding pavilion decorated with fresh flowers. The "Nādasvaram" (also called the "Shehnai" in North India) is an Indian musical instrument that traditionally accompanies most Telugu weddings.
