More resistant chromium-nickel grades can be passivated in a 20% by vol. nitric acid bath (Fig. 2). As indicated in the same table, less resistant stainless grades can be passivated by adding sodium dichromate to the nitric acid bath to make the solution more oxidizing and capable of formi...
In the lab I need some ferrous sulfate heptahydrate (FeSO4?7H2O). We have some old anhydrous FeSO4 from several years ago. It seems that at normal humidity, FeSO4 will hydrate to the heptahydrate on its own after a few days at most. Is this correct? Can I "hydrate" my FeSO4 just...
Despite short-term weakness innickel pricesand a bearish market, Chinese investments in projects to extract cobalt from nickel laterite ore using the high-pressure acid leach (HPAL) process, highlight a long-term strategy to secure critical resources for battery production, with the use o...

use lead-acid and nickel-metal hydride batteries, which are prone to leaking and causing a buildup of corrosive substances at their terminals. This guide will help you understand the general idea behind leaking batteries, why this happens, and the measures that can be taken to (safely) address...
Next, it's etched with acid and treated with a catalyst (a chemical reaction accelerator) to make sure that a coating will stick to its surface. Then it's dipped in a bath of copper or nickel (copper is more common) to give it a very thin coating of electrically conducting metal (...
The TRI Article Exemption can be difficult to track and report properly, oftentimes leading to fines. If your facility processes several different types of metal compounds (for example nickel sulfate and nickel oxide) you should base your TRI threshold determination on the total weight of all ...
We all want to do our best to take care of our skin, which is why it’s so important to make sure that we know what kind of ingredients are in our skincare and
Nickel cadmium(also called "nicad" or NiCd), the oldest and perhaps still best known types of everyday rechargeable batteries, respond best either to fairly rapid charging (providing it doesn't make them hot) or slow trickle charging.[10] ...
