Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. Applications 1.Steel Foundry: carburant/graphite electrode/refractory material 2.Industry Field: brake pad/seal ring/friction plate/heat exchanger/lubricity 3.Battery Production: alkaline battery cathode/lithium ion battery cathode 4.Metallurgy:casting for glass production/graphite crucible/ anodes for the aluminium, titanium smelting industry 5.Others:glass sheet/pencil lead/clay bricks/conductive coating We are the leading manufacturer of carbon additives in China for 10 years, mainly produce graphite petroleum coke, calcined petroleum coke, pet coke and silicon carbide , meanwhile we can trade metallurgical coke and foundry coke as your requirement. The products are widely used in metallurgy, chemical industry, steel-making, casting industry and many fields.
