Abstract

Amorphous aluminosilicates containing about 12 wto °/0 nickel
have been synthesized bycation exchange. Approximately 40°/0 of the nickel content is present in the form of octahedral [Ni\H20)6]2+ ions while the bulk of NF+ is coordinated both by I-hO molecules and by oxygen atoms of the aluminosilicate framework. When the materials are heated in air at 350 -c, a change in the nickel coordination environment/geornetry and possibly also a partial oxidation take place.
