• Nickel Oxides

Nickel Oxide specialists, Hart Materials, offers three types of product:

GNO bannerGreen Nickel Oxide (NiO)

Green Nickel Oxide is a chemically unreactive stoichiometric compound that contains 78.5% nickel metal. We specialise in the supply of high purity Green Nickel Oxides, which are available in three different size ranges. All of these are suitable for the production of Solid Oxide Fuel Cells and thermistors.

BLNO bannerBlack Nickel Oxide (Ni2O3)

Used in the manufacture of exhaust catalysts, Black Nickel Oxide is a non-stoichiometric chemical that contains approximately 77% nickel. It shows greater chemical reactivity than Green Nickel Oxide, particularly in acidic media. We supply high purity grades of Black Nickel Oxide in two particle size ranges.

BNO bannerBrown Nickel Oxide (NiO)

Brown Nickel Oxide is a less expensive, commercial grade of material, used for colouring glass. It contains slightly higher levels of copper, cobalt and iron, than Green and Black Nickel Oxide. Free from metallic nickel, it is available as a moderately fine powder with a typical size of 97% below 25 microns.
