Calcined Anthracite

Ningxia Taixi Anthracite coal is famous in the world. Apart from as a fuel directly, it also can be calcined into GCA and ECA according to different application.

Using high-quality Ningxia Taixi Anthracite as the raw material, gas calcined anthracite coal is a kind of product which should be refined and chosen, then dry-distillated in 1250°C in order to reduce the volatile matter content, and enhance the fixed carbon content and oxidation resistance. It is an essential material used in casting to adjust the carbon content and oxygen content of the molten steel.

Electrically Calcined Anthracite (ECA) is also made from selected high-quality Taixi Anthracite subject to calcinations inside single-phase AC roaster under 2000°C. There are lots of physical and chemical changes during roasting: before 1200°C is a process of dehydration and dehydrogenation while desulfurization happens during  1400-1600. Real density and resistivity will be decreased with the temperature increasing. ECA is the main material of carbon electrode paste and also widely used in cathode blocks for aluminum industry. ECA is also used in casting as same as CAC.
