As its name suggests, synthetic graphite is graphite which is created through manufacturing, rather than natural graphite which is mined. High-quality graphite can be manufactured as a by-product of the steel-making process. In steel-making, a substance called kish is skimmed off the molten iron. Kish is composed of iron, graphite and slag.

Density can give a measure of crystal perfection and in practice, synthetic graphite rarely exhibits a density above 2.0 g/cm3 with some versions as low as 1.6 g/cm3. The density of synthetic graphite is directly related to the pore size and decreasing the particle size, or grain, reduces the relative porosity.
Name of the Technology: High density graphite Summary: High density graphite is a very special material with high density, high strength and fine micro- structure. It can be used for variety of applications because of its ability to withstand extremely high temperatures while maintaining its strength and shape.
