PI-KEM and PI-KEM Hart nickel oxides are used by a variety of industries, including ceramics, electronics, energy, and aerospace. They are known for their high quality, reliability, and performance.

We supply nickel oxide in two formulations:

Stoichiometric Green Nickel Oxide (NiO)
Non-stoichiometric Black Nickel Oxide (Ni₂O₃)

Each has its own characteristics and applications (See product overview below). Green and Black Nickel Oxide are available in ‘A’ and ‘F’ size ranges.

Novamet nickel oxide powders are specially formulated for high-density alloys and tailored for sintering applications, boasting exceptional compactability and metallurgical attributes.

Applications of nickel oxide include:

Solid oxide fuel cells (SOFCs) as the anode material and Solid oxide electrolyser cells (SOECs) as the cathode material‍
Semiconductor electronics: heat-sensitive thermistors and voltage-dependent varistors
Catalysts: As a catalyst in a variety of chemical reactions, including hydrogen production, methane reforming, and carbon monoxide oxidation
Glass and ceramic colouring: Used as pigment for glass and ceramics in a variety of shades of brown and green
Batteries: Used as the cathode material in nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries
Fuel cells: Used as the anode material in direct methanol fuel cells (DMFCs)

Nickel Oxide Type	Description
Green Nickel Oxide	• 78.5% Nickel • Prepared by the controlled oxidation of nickel powder, which has been derived from the thermal decomposition of nickel carbonyl gas • Excellent dispersion in matrix materials and high corrosion resistance • Standard Grade: mean particle size 2-3 µm in three-dimensional chains of 12- 16 µm •'A' Grade: discrete particles with mean particle size 6-10 µm •'F' Grade: discrete particles with mean particle size 1-2 µm • Used in SOFC and precision electronics manufacture
Black Nickel Oxide	• 76.4-77.6% Nickel • Superior resistance to oxidation, excellent thermal stability and enhanced electrical conductivity • The very high BET surface area (typically 60-100m²/g) gives the powder a very high reactivity • 'A' Grade: Mean particle size Microtrac D50 6-10 µm • 'F' Grade: Mean particle size Microtrac D50 1-2 µm • Used in electronics industry for manufacture of ferrites and other products, to colour glass and porcelain, and in catalytic applications
