T255™ Nickel Powder (Standard Grade)
T255™ is a high purity nickel powder with a fine, threedimensional filamentary (“chain-like”) structure. T255™

is produced by a unique carbonyl gas refining process at the Clydach Nickel Refinery in the UK.
T255™ is recognized as an industry standard feed for the production of sintered rechargeable battery electrodes: •

Sinters readily to form a conductive, open porosity network • Uniform size distribution and density results in controlled porosity in

sintered electrodes and other porous structures • Porosity-strength relationship of sintered T255™

is well understood, enabling tailoring of porous structure
T255™is widely used as a conductive additive in: • Batteries and fuel cells • Pigments in coatings,

especially for electromagnetic interference (EMI) shielding applications • Polymers for electronic applications to provide electrical conductivity
T255™ is also used in powder metallurgical applications, as the filamentary structure can be broken down into fine primary particles.
T255™ is produced in compliance with the following ISO standards: ISO 9001:2008, ISO 14001:2004 and ISO 18001:2007.
