. GPC has a granular form and can dissolve well in the molten iron, making it more fluid and allowing graphite to play a stronger role in the molten iron, which can improve the quality of the product in casting.
3. In the cast iron industry, GPC is also used as an inoculant to enhance the carbide pellets in the molten iron.
4. Used for making high temperature crucible in smelting, lubricant in machinery industry, making electrode and pencil core; widely used in metallurgy industry as high grade refractory material and coating, stabilizer in military industry, pencil core in light industry, carbon brush in electrical industry, electrode in battery industry, catalyst in fertilizer industry, etc.
5. It can also be used in the manufacture of brake pads and the production of wear-resistant materials.
