| titleOfInvention | A method of producing a self-hardening molding sand or core PL |
| abstract | A method of producing a self-hardening molding sand or core by mixing quartz flour in the amount of 60-75% by weight with hydrolyzed ethyl silicate in the amount of 24-39% by weight, and then with a 10% aqueous solution of acidic ammonium carbonate in the amount of 0.6-1.0 % by weight, characterized in that the quartz flour is tridimized by introducing potassium K + ions and aluminum Al3 + ions or sodium Na + ions and aluminum Al3 + ions in the amount of 2-10% by weight in relation to the amount of flour, and then calcined at 900- 1000 ° C for 5-7 hours, the hydrolyzed ethyl silicate contains 15.9-30.1% by weight of silica and is preferably subjected to a magnetic field.
