The Difference between Graphite Petroleum Coke(GPC) with Calcined Petroleum Coke(CPC)

Jinju graphitized petroleum coke and calcined petroleum coke supplier will explain the difference between these two products to you. I believe you will gain something after reading this article. We provide you with high-quality graphitized petroleum coke and calcined petroleum coke products.

Jinju graphitized petroleum coke and calcined petroleum coke suppliers explain the difference between these two products.

1. Different processing methods: Calcined petroleum coke is preheated at high temperature under air-tight conditions, usually at a temperature of more than 1500°C to remove volatiles and moisture in the raw materials, thereby improving its physical and chemical properties. Graphite petroleum coke is made by placing petroleum coke in a graphitization furnace and undergoing a high-temperature graphitization process of about 3000°C.

2. Different application areas: Calcined petroleum coke is widely used in metallurgy, chemical industry, machinery, power and other industries as a carbon-increasing material and reaction intermediate.

Graphite petroleum coke is mainly used for high-quality steel, special steel sleeves and related metallurgical and foundry industries as a carbon-increasing agent, and is also used as an additive for plastic and rubber products.

3. Different appearance: Calcined petroleum coke is irregular in shape and black block particles of varying sizes, with a strong metallic luster and transparent carbon particles. In addition to the appearance of calcined petroleum coke, graphitized petroleum coke is darker and brighter than calcined petroleum coke, and has a stronger metallic luster. It can also be drawn directly on paper smoothly.

The above three points are the differences between graphitized petroleum coke and calcined petroleum coke.
