As a regular crystal, we, these forms of solid, often taking beautiful indeed tend to think - will face in sparkling diamonds, or in the form of ice like snowflake. However, graphite - pencil lead. "- Is also a scientist crystal, glass, solid material having a molecular structure is as follows regular structure.

The Carbon graphite can be formed in any shape and size substantially from a huge range of the material. While the individual graphite crystals they are barely visible, Giant's Causeway in Ireland is made the same height as the basalt crystal Oto 4-storey building. You can be different from each other to produce crystals surprisingly single element. You will be able to kristaliz hour at a party in the form of a delicate snowflake water, or ice. All crystal diamond, graphite, charcoal, and carbon. But why then is very difficult diamond, rather than a pencil lead, not only as a lubricant, it is to be used, it is graphite soft?

In scientific terms, the crystal has two different types: constructing a framework having three dimensions, as in graphite, they are composed of layers, a kind of diamond.

Regular chemical structure capable of binding tight, is attached to the nearest neighbor on each side, each carbon atom of the upper and lower diamond. In the same way as regular - - good from graphite very well, however, there is as above and the following few. Thin carbon layer, the link is lanky It was shear easily, it can write a page or can be, drawn in pencil, graphite layer to stick it away as this is a high quality "soft". Bonds present in the Flake graphite is meant that the atoms can slip by, it should be used as a solid lubricant.
