FIELD: foundry production.
SUBSTANCE: composition for manufacturing moulds contains 50-60% by weight of fine struvite with a particle size of not more than 10 microns as a filler and 40-50% by weight of colloidal silica gel from magnesium hydrosilicate with 41-50% moisture as a binder.
EFFECT: use of production waste is ensured while maintaining the quality of the surface of the resulting ceramic moulds.
