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, …

Therefore, in the present work, the refractory properties of synthetic aluminosilicate generated by blending virgin silica sand with processed alumina are presented. This is essentially an exploratory investigation that seeks to provide the foundation for

the subsurface. Most commonly, silica sand is used as the model porous medium. Iron oxides have been used as well, mainly in form of iron-oxide-coated silica sand. Clay minerals, however, have only been recently used as model porous media, and the coating of aluminosilicate clay minerals on silica still needs investigation.
