amorphous graphite brake lining in uzbekistan

Natural flake graphite is formed when carbon material is subjected to high pressure and high temperature The carbon source material can be either organic or inorganic although most commercially sourced flake graphite comes from organic deposits The pressure required is usually greater than 1 gigapascal 75000 psi and the temperature needed is usually higher than 750 degrees Celsius
