Chemical element of an element to exist in one of many structural forms is known as 'allotropy'. The standard state, also known as the reference state, of an element is defined as its thermodynamically most stable state at a pressure of 1 bar and a given temperature (typically at 298.15 K). In thermochemistry, an element is defined to have an enthalpy of formation of zero in its standard state. For example, the reference state for carbon is graphite, because the structure of graphite is more stable than that of the other allotropes. Several kinds of descriptive categorizations can be applied broadly to
Element Six vapour deposition technology opened the opportunity to synthesize diamond films and a new raft of application areas became possible. In 2002, the company changed its name to Element Six and its business focus moved towards building an enterprise based on advanced material applications for increasingly sophisticated engineering customers backed by global technical support and a strong research and development organization. In 2013 Element Six opened the world’s largest and most sophisticated synthetic diamond research and development facility. The Global Innovation Centre, near Oxford, UK develops a pipeline of innovative synthetic diamond and related supermaterial products for customers, in industries from
