The Institute of Electronics Materials Technology (ITME) in Poland started to produce high quality large graphene sheets.

The graphene production is done on a SECO/WARWICK reactor, co-financed with government aid under the Grafmet project. It utilizes an all-metal thermal work zone and a high vacuum system with turbo molecular pump to allow production of graphene sheets in sizes up to 500 x 500 mm.

This Reactor is the first one of its kind produced in Poland, and allows graphene to be produced in large sizes utilizing epitaxial growth by Chemical Vapor Deposition (CVD).
