This three-dimensional structure accounts for the physical properties of graphite. Unlike diamond, graphite can be used as a lubricant or in pencils because the layers cleave readily.

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out.How molten carbon crystallizes into ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, ...

Our results show nanosecond formation of the diamond structure after shock compressing pyrolytic as well as porous polycrystalline graphite samples.

The Structure of Graphite Back to See Inside a Diamond Click and drag the molecule to rotate it. PC users - click right button in window for options. Mac users - click and hold mouse button for ...

Credit: Ralf Riedel But preparing samples of this hexagonal structure large enough to analyze has been challenging. What's more, the presence of other contaminating forms of carbon in the original ...

Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms, called allotropes, including diamond and graphite. Scientists have now discovered a new form of ...

A new ultra-hard form of carbon may exist between graphite and diamond.

Scientists at Stanford University have found a new way of creating artificial diamonds out of graphite (the material in your pencil leads), without applying external pressure of any sort.

Rare diamonds found in meteorites called ureilites have a folded hexagonal structure. Learning the process of how they were formed could inspire better lab-grown diamonds.

A new kind of diamond is now in town, according to researchers. These are apparently 58% harder than ordinary diamonds.
