Silicon(IV) bromide because of it’s near similarity come Silicon Tetrachloride has actually several distinct features, applicable in the production of ultrapure silicon for the produce of semiconductor devices. This product has an advantage over SiCl4 in the rate of silicon deposition. Pyrolysis that Silicon(IV) bromide followed by treatment through ammonia yields Silicon Nitride (Si3N4) coatings. This tough compound is offered for ceramics, sealants, and also the production of countless cutting tools. That is additionally used in water treatment, chemical analysis and in ultra high purity for particular crystal growth applications. Synthetic of this product has actually been reported (see the web links below).
