Abstract

The mold uses quartz moulding sand and an aluminium oxide binder. The quartz sand has a particle size range of 0.05 to 5 mm and the aluminium oxide has a particle size of 1 to 200 mu m. The binder is arranged as a coating layer over the surface of the sand and contains an aqueous glass phase which draws together along the contacting faces of the quartz particles in knuckle manner and has a micro-porous structure in the boundary phases. Foundry moulding mixture is used to produce mould or moulding blank with additions of broken or ground emulsion-free aluminium oxide and an aqueous glass based binder. Independent claim describes method for manufacturing mould by mixing binder-oxide mixture with moulding sand and casting it under pressure in moulding box and drying liquid binder to produce micro-porous binder bridges between individual quartz sand particles.
