    摘要: Moulded articles are produced by heating expandable graphite, in which the expandable graphite is first pre-expanded at 140.degree. to 450.degree. C. until a bulk density of 30 to 500 g/l has been reached, at least 50% by volume of a mould is then filled with the graphite thus pre-expanded, and the expansion of the graphite is then completed in the mould by heating to temperatures in the range from 300.degree. to 700.degree. C.
