US5911269A - Method of making silica sand molds and cores

Thermal expansion defects, i.e. veining, are reduced in iron, steel, and nonferrous castings by adding a lithia-containing material in a sufficient amount to the silica sand mold to provide about 0.001% to about 2.0% of lithia. The addition of lithia is accomplished by adding lithium bearing minerals such as α-spodumene, amblygonite, montebrasite, petalite, lepidolite, zinnwaldite, eucryptite
