Abstract

The invention concerns a mineral composition for preparing foundry moulds comprising (a) from 20 to 90 % by weight of gypsum (b) from 10 to 80 % by weight of a mineral component made from silica and/or alumina and (c) from 0.5 to 4.8 % and preferably from 1.5 to 4.5% by weight and in particular between 2 and 4.5 % by weight of a mineral powder having a thermal conductivity (ŋ) at 20 °C greater than 15W/(m.K) and a specific surface area greater than 10 m/g these percentages being relative to the total weight of the sum of components (a) (b) and (c).
