A gray-black, metalliferous, tiny six-square crystal or powder. d17 5.778;d 5.64. Melting point 408 ℃; Soluble in liquid ammonia, ethanol, hydrochloric acid, hydrogen iodide and potassium iodide solution, insoluble in cold water. It is decomposed into bismuth oxide in hot water. Heat to 439 °c (760mmHg) sublimation, decomposition when raised to 500 °c.
excess iodine was dissolved in a saturated solution of stannous chloride in concentrated hydrochloric acid, and a saturated solution of bismuth trioxide in hydrochloric acid was added. After precipitation of bismuth triiodide crystals, vacuum drying was performed. First heated to the melting point below, then strengthen the heat to sublimate, namely pure bismuth triiodide.
assay reagents for the detection of palladium, alkaloids, or other bases.

Introduction | bismuth iodide also known as bismuth iodide. BiI3 = 589.69, gray-black hexagonal crystal or powder with metallic luster. Heat sublimation in an inert gas. Soluble in alcohol, hydrochloric acid, hydroiodic acid and potassium iodide solution, slightly soluble in liquid ammonia, benzene, toluene, insoluble in cold water. The air is gradually decomposed. It was also decomposed in case of strong acid. The powdered bismuth is mixed with iodine, ground, heated to react, or the iodine is dissolved in a saturated solution of concentrated hydrochloric acid in tin dichloride, and bismuth trioxide is added. |
Application | bismuth iodide as a layered material expands the two-dimensional material family, the bismuth iodide nanosheets expand a new two-dimensional material, can be applied to radiation detectors, X-ray detection, etc., the vertical Heterojunction and the preparation of electrical, photoelectric devices for the discovery of new electronic, optoelectronic devices offer new possibilities. Based on its unique two-dimensional layered structure, two-dimensional bismuth iodide has many excellent properties. The band gap of bismuth iodide is relatively wide, and the atomic numbers of Bi and I can be applied to radiation detectors, X-ray detection, and the like, as compared with BiI3. |
