Zenyatta Ventures Ltd says that its graphite powder has been deemed suitable for a range of applications by Ben-Gurion University (BGU), Israel.

The purified graphite material was tested by the university’s R&D team on dispersion and application for composite property enhancement on drug delivery and hydrogen storage devices.

‘BGU regularly uses various types of commercially available natural flake graphite but found Albany graphite to exfoliate under sonication much easier and with higher yields of graphene nano-particles than any other natural graphite types that we have tried,’ said Dr Oren Regev and Dr Ilan Pribar of the Department of Chemical Engineering at BGU. ‘The Zenyatta graphite appears to be composed of smaller and cleaner particles with a narrower particle size distribution. We believe that this is a high value special material with unique characteristics that could make Albany graphite the preferred material for conversion to valuable graphene applications.’

‘Thermogravimetric analysis (TGA) by BGU on Zenyatta material found it to be completely different from any other natural graphite flake products studied so far in our lab,’ added Dr Regev. ‘As a matter of fact, it is the same order of magnitude as commercially available Graphene Nano Platelets (GnP) derived from more expensive sources.’
