The silicon carbide has theadvantagesofexcellent corrosion resistance, high coefficientofheatconductivity, self-lubricity, small expansion. It canbewidelyused in the petroleum, chemical,machinery-building,cosmonauticsand motors industries. Thefrictional factor ofcombination ofsilicon carbide and carbongraphite is the least, soit widelyapplied to high characteristicsfor themechanicalseals.
