Nickel salt occurs most usually in combination with sulfur and iron in pentlandite, with sulfur in millerite, with arsenic in the mineral nickeline, and with arsenic and sulfur in nickel glance. Our range of nickel salt includes nickel salt powder, nickel nitrate, nickel sulphate, nickel carbonate, nickel oxide, nickel chloride. Nickel Nitrate We offer nickel nitrate which is a chemical compound Ni (NO3)2 or any hydrate thereof. Widely demanded by various industries for chemical synthesis process and several chemical reaction processes, some of nickel nitrate properties are as follows:Properties · Molecular formula Ni(NO3)2.6H2O · Molar mass 182.7032 g/mol · Appearance green hygroscopic solid · Density 2.05 g/cm3, solid · Melting point 56.7°C (329.85 K) · Boiling point 137°C (410.15 K) · Solubility in water For the hexahydrate: 238.5 g/100 ml at 0°C chromium sulphate specifiactions: Cr2(SO4)3·6H2O : 98 Fe : 0.001 Ca : 0.001 K : 0.002 Al : 0.006 water-fast : 0.01 Shanghai Liangren Chemical Co.,Ltd Tel: +86-21-69577128 Fax : +86-21-59585627 Contact : Miss tracy Mob: +86-15221350576
