| Application | antimony iodide is an important dopant for thermoelectric materials and can be used as a raw material for the preparation of catalysts in the chemical industry, and used in the pharmaceutical field, a wide range of uses. |
| preparation | A High Borosilicate glass tube with a length of about 700mm, a diameter of 10mm and a wall thickness of was sealed at one end, after rinsing, soak in aqua regia for 3 hours, take it out, rinse it repeatedly with deionized water, bake it at 120 ℃ for 6 hours, and dry it until it is ready for use; weigh 19g of 99.99% pure iodine powder into a glass tube, weigh 6g of 99.999% pure antimony block crushed to about 2mm to cover the iodine powder, then vacuum it to 15Pa and seal, put it in a sealed steel pipe and put it in a rocking furnace with a constant temperature of 380 ° C. After 20 minutes, it starts to swing for 10 minutes, with a swing amplitude of about 45 degrees, 3 to 5 times/minute, and stops for 30 minutes, the rocking was continued for 10 minutes and stopped for 30 minutes. After 2 hours of circulation, the product was removed from the furnace chamber and naturally cooled. The product was collected and weighed 24.75g. The yield of antimony iodide was 99% and the purity was 99.996%. |
