| titleOfInvention | IMPROVED BINDERS FOR FOUNDRY MOLDS AND MOLDS |
| abstract | The present invention relates to a method of forming a foundry mold or core, which comprises adding a binder to the refractory particles, including an alkali metal salt of a polybasic organic acid or a polymerized monobasic organic acid, together with an alkaline earth metal hydroxide and one or more polyvalent metal oxides and water and passing an acid gas through the resulting body, the organic acid having a pKa of not less than 2.5 and the alkali metal salt solution, before the addition of the alkaline earth metal hydroxide, having a pH of not less than 5.7, characterized in that calcium citrate is present in the binder and the total weight of the alkaline earth metal hydroxide, calcium citrate and the polyvalent metal oxide (s), comprising between 25 and 500 percent by weight of the organic acid salt. |
