  • US Patent for 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 .alpha.-spodumene, amblygonite, montebrasite, petalite, lepidolite, zinnwalditeSilicas-Manufacturing process ,Technology, Applications,The company produces lump silica and silica sand of various sizes. Fine sand products are sold in the Maritimes, Quebec, and the northeastern United States for use in sandblasting, filter sand, traction sand, cement and concrete manufacturing, refractory use and decorative sand, and as a flux for ase-metal smelters; the sand could also be used

    The biofilm becomes more stable, alginate production increases and filtration performance gradually decreases until a point when a media change is required. Glass Media and Sand. Glass is an aluminosilicate manufactured from silica sand or from the re-melt of glass bottles.Glass Chemistry Encyclopedia structure, reaction,common form of silica is sand, but it also occurs in nature in a crystalline form known as quartz. Pure silica can produce an excellent glass, but it is very high-melting (1,723 o C, or 3,133 o F), and the melt is so extremely viscous that it is difficult to handle. All common glasses contain other ingredients that make the silica easier to melt and the hot liquid easier to shape.
