But since the 1990s its use has been prohibited or highly regulated because of its toxicity, and many manufacturers have shifted to trivalent chromium, which is less toxic. Honda wanted to create ...

Chemists report that radiation-induced chemical reactions may help mitigate the corrosion of metals in a new type of nuclear reactor cooled by molten salts. High temperatures and ionizing ...

The distribution of chromium ion oxidation states — how many electron vacancies these ions have available for chemical reactions — may be the factor that determines whether corrosion occurs. "The ...

“The presence of dissolved trivalent chromium [Cr 3+, with three electron vacancies] can accelerate corrosion in some cases, whereas divalent chromium [Cr 2+, with just two vacancies] does not ...
