Graphite Block

SKU: 0003

Graphite Block is a solid shape of graphite that is widely used in various industries. It can be made from artificial graphite, graphitized graphite electrode, or graphite powder isostatic pressing. 

  • Product Info

    Graphite Blocks are known for their high purity, with a fixed carbon content greater than or equal to 99.9%. They are used for a variety of purposes such as flexible graphite sealing materials, and as a substitute for platinum crucible for melting chemical reagents. They also serve as a base for lubricants, high purity graphite block for silicon carbide furnace, graphite furnace, and other metallurgical furnaces. 

    In addition, they are used as furnace resistance furnace lining and conductive materials, as well as impermeable graphite heat exchanger. They are widely used in electronics, metallurgy, chemicals, steel, and other fields.
