70 refractory products, lubricants, friction linings, powder metallurgy, pencils, nuclear technology, fuel cells, etc.), cryptocrystalline (“amorphous”) graphite is not suitable for battery production or for applications in nuclear and powder metallurgy. Coarse-grained lumps are primarily used for the production of high-quality products.
