Natural graphites - Import export

Special processing methods are used to produce what is known as exfoliated graphite or expandable graphite from natural mineral graphite. It has the unique property of abruptly expanding by many times its volume when it is exposed to heat. At Georg H. Luh, we have extensive know-how in this product field and offer the right products for a wide variety of applications with numerous different grades and variants.

Graphite, like diamond, consists of pure carbon arranged in a hexagonal crystal system. One differentiates between natural and synthetic graphite depending on the extraction or production method. Graphite exhibits a unique combination of material properties due to the special crystalline composition of the layer structure.
