Graphene Block<\/div>\n
\n

Features of Graphene Block<\/h2>\n
The Graphene Block is a high-performance graphite block manufactured using graphene as a raw material and produced through a proprietary forming technology. Conventional graphite blocks (isotropic graphite) have an isotropic structure and offer excellent mechanical strength. However, their thermal and electrical conductivity are generally inferior to those of metals. In contrast, the Graphene Block exhibits extremely high anisotropy and excellent crystallinity, providing exceptionally high thermal conductivity and electrical conductivity compared with conventional graphite blocks (isotropic graphite). It also has a low coefficient of kinetic friction, giving the material distinctive performance characteristics as a solid lubricant. Furthermore, the combination of high ultrasonic attenuation and high thermal conductivity makes the Graphene Block particularly useful as a backing material for ultrasonic probes, where efficient dissipation of heat generated by the ultrasonic transducer is required.\n<\/div>\n

Machined Graphene Block Components<\/div>\n

Features of Machined Graphene Block Components<\/h2>\n
Graphene Block is a high-performance graphite block manufactured from graphene using our proprietary forming technology. <\/div>\n
Because plates are produced by slicing them from the block, the direction of thermal conductivity can be controlled by changing the orientation in which the plates are sliced. Depending on the slicing orientation, components can be produced with high thermal conductivity either within the in-plane direction or and the thickness direction.\n<\/div>\n

Depending on the slicing orientation, components can be produced with high thermal conductivity either within the in-plane direction or and the thickness direction.\n<\/div>\n
The amount of heat that a heat-dissipating material can transfer depends not only on its thermal conductivity, but also on its \u201cthickness.\u201d In general, a thicker component can transfer a greater amount of heat. Conventional graphite-based heat-dissipation materials face a trade-off: materials with high thermal conductivity are typically restricted in thickness, while thicker materials tend to have lower thermal conductivity. As a result, their applications have been relatively limited.\u3000<\/div>\n
By using graphene as a raw material and processing it into high-density, highly anisotropic graphite, our graphene block components can be manufactured with thicknesses more than 100 times greater than conventional products. This enables high heat dissipation performance in general-purpose applications where graphite-based thermal components were previously difficult to utilize.<\/div>\n
