14.4A: Graphite and Diamond - Structure and …

Graphite has a high melting point, similar to that of diamond. In order to melt graphite, it isn''t enough to loosen one sheet from another. You have to break the covalent bonding throughout the whole structure. It has a soft, slippery feel, and is used in pencils and as a dry lubricant for things like locks. You can think of graphite rather

Ferrosilicon - Wikipedia

2019-4-23 · Unlike gray cast iron, which forms graphite flakes, ductile iron contains graphite nodules, or pores, which make cracking more difficult. Ferrosilicon is also used in the Pidgeon process to make magnesium from dolomite. Treatment of high-silicon ferrosilicon with hydrogen chloride is the basis of the industrial synthesis of trichlorosilane.

Models of kinematics dependent anisotropic and

Bowden and Tabor, 1956, Bowden and Tabor, 1958, Bowden and Tabor, 1964 and Tolansky (1960) reported early experimental studies devoted to the anisotropic friction and the directional abrasion resistance on faces of diamonds. The coefficient of friction of diamond on diamond is strongly dependent on the sliding direction, varying by up to a factor of three on some crystal faces.
