FOUNDRY ADDITIVE BASED ON GRAPHITE

摘要

The invention relates to a foundry additive which contains a finely ground, preferably microcrystalline or amorphous graphite. Said graphite has an average particle size of D50 of less than 100 µm and preferably an average crystallite size of less than 70 nm. The invention also relates to a moulding material mixture which contains the foundry additive, to a method for producing said foundry additive, to a foundry mould made from a grainy, fire-proof moulding material which contains the foundry additive and to the use of the foundry mould for the cast metal.
