Vision

To become world leader in the field of carbon and graphite products by leveraging our core competence and by research and development on advanced materials.

Mission

HEG R&D Center for carbon science and technology will have strong applied research and development focus in the field of conventional carbon products and advanced carbon materials/ products such as carbon nanotubes/fibers.

It will push the technology envelope and shall establish a strong cooperative research effort (Industry / Government / University) to improve energy efficiency, process productivity and quality control of carbon products with environmentally responsible approach both in its operations and in its products that purify the environment. It shall develop new secure sources of high quality carbon feed stocks that can be used by a number of different carbon manufacturing processes and new carbon and graphite based products.
