Features graphite
The conductivity of
graphite has good electrical conductivity.&©|160;With increasing temperature, the electrical conductivity increases.&©|160;In this regard, the temperature coefficient of resistance of the graphite, in contrast to metals, graphite negative.
Electrical resistivity
resistivity-physical quantity characterizing a substance prevent the passage of electric current.&©|160;The higher the density of graphite, the lower resistivity.&©|160;
Measure: Ohm * m
Thermal conductivity&©|160;
The thermal conductivity of graphite is higher than many metals, and decreases as the temperature increases.&©|160;The thermal conductivity of the graphite varies depending on the treatment temperature.&©|160;
Measure: W / (m * K)
Heat Resistance
Graphite does not melt but sublimes at a temperature of 3900 ¡ã K and withstands harsh temperature changes.
Wettability of the&©|160;
graphite is not wetted by most molten metals and molten glass.
Oxidizability&©|160;
In the presence of excess air Graphite begins to oxidize at 750 ¡ã K.&©|160;Graphite is not soluble in solvents and inorganic organic origin, does not interact with many acids, alkalis and salts.
Mechanical strength
graphite Tensile strength, compressive and bending strength increases with increasing temperature up to 2700 ¡ã C, and only then begins to decline.
Mechanical strength values of graphite characterize such as&©|160;&©|160;tensile strength in bending&©|160;&©|160;and&©|160;&©|160;compression strength&©|160;.&©|160;With increased density, both of these quantities are increased.&©|160;Unit: ***.
Purity&©|160;
All graphites contain in its structure in greater or lesser amounts of minerals (ash).&©|160;Special graphite purification technology allows to reduce the ash content to 10&©|160;-4&©|160;-10&©|160;-5&©|160;&©|160;wt% with ash content of 0.5% in the starting materials.
Machinability&©|160;
Graphite is well machinable;&©|160;its properties and structure allow to produce products of complex shapes with tight tolerances and high precision.&©|160;The |
