Traces of vanadium in significant-temperature combustion products and solutions form droplets of molten vanadates. These attack the passivation layers on metals and result in higher temperature corrosion, that's a priority specifically for internal combustion engines. Molten sulfate and lead particulates also have this kind of result. )[18] Magnetic remanence, https://broadfar.com/nuso-heated-tobacco-smarter-alternative-to-traditional-smoking/
