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.
