The soldering for providing a kind of hydrochloric acid corrosion resistant alloy has a corrosion resistance to hydrochloric acid, when soldering, can be used for various types of stainless steels solderings in practical temperature (1150 掳C or smaller), has good bonding strength and be brazed ...
The four halides form nickel compounds, which are solids with molecules with octahedral Ni centres. Nickel(II) chloride is most common, and its behavior is illustrative of the other halides. Nickel(II) chloride is made by dissolving nickel or its oxide in hydrochloric acid. It is usually found...

Hydrochloric acid (HCl) leaching treatment was used to remove the redundant Ni metal (HCl-Ni@C). After HCl treatment, hollow onion-like carbon nanoshells along with little Ni nanoparticles protected by graphene layers remained. We then applied electrochemical cyclic-potential on the HCl-Ni@C ...

Pluronic P123 copolymer (99%), hydrochloric acid (HCl, 36.5%), cetyltrimethylammonium bromide (CTAB, 99%), ethyl alcohol (C2H5OH, absolute), and ethylenediamine (EDA, ≥ 99%) were purchased from Sigma-Aldrich. Tetraethyl orthosilicate (TEOS, 98%), carbon tetrachloride (CTC, ≥ 99.5...
Nickel chloride (hexahydrate) is obtained by reacting metal nickel powder or nickel oxide with hot, dilute hydrochloric acid. Definition hexahydrate: A crystalline compoundthat has six moles of waterper mole of compound. Preparation Nickel(II) chloride can be obtained by reaction of the elements eit...
kerosene) to aqueous (pH 8) phase ratio in 60 min. The nickel in the organic phase is readily stripped from the extractant, with more than 95% recovered, along with low levels of zinc (1.7 mg/L) and cadmium (0.6 mg/L), following a 0.5 M hydrochloric acid or 1 M nitric acid ...
Dilute mineral acids attack nickel to a varying extent. The metal dissolves readily in dilute nitric acid. Evaporation of the solution forms emerald green crystals of nickel nitrate hexahydrate, Ni(NO3)2•6H2O. Actions of dilute hydrochloric and sulfuric acid on nickel are relatively slow: slower...
