Graphite II (Hexagonal) Crystal Model

Graphite, a low temperature dimorphic form of carbon, belongs to the hexagonal crystal system. Various physical properties may readily be explained from its structure. Carbon atoms are tightly arranged in hexagonal layers with distances between adjacent atoms in one layer considerably less than those of another layer. Because attractive forces between carbon atoms of different layers are weak, one layer slips easily over another. This accounts for the softness of graphite and its lubricating (greasy) properties. Graphite has a lower specific gravity than the diamond because carbon atoms are further apart. The mobility of electrons between layers is the reason for its excellent electrical conductivity.

This model is hand made in the USA by Klinger Educational Products. This is a permanent structure. We only use grade A materials. The 1 inch balls are made of hard Maplewood that includes an enameled painted finish. Polished steel rods are used to connect the wooden balls together.

Graphite 11 contains 59  -  1 inch balls.
