Product Description
Calcination refers to the heat treatment of anthracite at high temperature (usually 1200-1500ºC) to remove volatile matter, moisture and impurities, and increase carbon content and structural stability. After calcination, anthracite has a higher fixed carbon content (up to more than 90%), lower ash and sulfur content, and better electrical conductivity and high temperature resistance.
Calcined anthracite is used for carburizing of various electric smelting furnaces, casting steel and iron, chemical environmental protection: water treatment filter material, flue gas desulfurization adsorbent carrier. It is used to make aggregates for graphite electrodes, cathode carbon blocks, and lithium battery negative electrode materials to enhance conductivity and structural strength.
