Product Description

Product Description

 GRAPHITE BLOCK
 
Graphite is a crystalline carbon. It is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb) covalently bonded to form a covalent molecule. 
 
Since each carbon atom emits an electron, those electrons can move freely, so graphite is an electrical conductor. Graphite is one of the softest minerals, and its uses include the manufacture of pencil leads and lubricants. It is chemically inactive, resistant to corrosion, and hard to react with acids and alkalis.

Our products have the advantages of high density, low electrical resistivity, anti-oxidation, anticorrosion, thermostability, good electric conductivity, etc. It's widely used in Powder metallurgy, Casting molds and furnace parts for hot metal, Crucibles for melting and alloying, Quartz processing, and semiconductor industries.
 
Carbon blocks are used for thermal energy storage, where electricity heats the blocks to ultra-high temperatures (over 2000°C) for storage. This stored heat is then released on demand to provide thermal energy or converted back to electricity using thermophotovoltaic (TPV) panels. This technology offers a low-cost, scalable, and efficient method for grid-scale energy storage, particularly for industrial applications that require significant thermal and electrical power.
