Tin Iodide Powder

Tin Iodide Powder

Introduction

Tin iodide powder is an inorganic compound composed of tin (Sn) and iodine (I). It is typically found as a yellow crystalline powder and is known for its semiconducting properties. Tin iodide is often prepared by reacting tin metal with iodine under controlled conditions or by using tin salts and iodine. Its chemical formula is SnI₂, and it is most commonly available as a fine powder for use in various industrial, chemical, and technological applications.

Tin iodide exhibits properties such as semiconductivity, making it useful in optoelectronic devices, and chemical reactivity, allowing it to be utilized as a reagent in synthesis and catalysis. It is soluble in some organic solvents like acetone and benzene, but it is insoluble in water. Its optical bandgap and photoactive nature have driven research into its potential in energy-related technologies such as solar cells and photodetectors.
