FIRE-RESISTANT DISPOSAL AND ELASTIFIERS FOR SEMINS AND METHOD FOR THE PRODUCTION THEREOF

摘要

Mixture, especially for the production of refractory moldings, comprises (a) a refractory metal oxide main component, (b) an elasticizing component containing the mineral emery, which consists mainly of Fe2O3 and Al2O3, and (c) optionally a binder component, e.g. lignin sulfonate. ??Independent claims are also included for the following: ??(1) The production of this mixture by treating the main component with emery and mixing; ??(2) The use of emery as elasticizer for refractory moldings or compositions.
