NICKEL META-SILICATE Chemical Properties,Usage,Production
Preparation
Stoichiometric quantities of NiO and SiO2 heated to 1500° combine
to give green Ni2SiC>4 with the olivine structure ; a green transparent spinel phase is obtained
from this at higher temperatures and under pressure. A green hydrated silicate
NiSiO3?xH20 (x = 1-3) is precipitated from nickel(II) solutions by Na2SiO3.
