Soda/Lime glass is made from silica sand and uses sodium carbonate and lime as a flux. Historically, the sodium carbonate component was made by burning barilla (a coastal shrub).

Resin silica sand is one of the best moulding sand for cars, tractors and hydraulic parts. resin silica sand also can be used for many casting methods such as vacuum casting, VRH, LFC, investment casting, common and resin sand., LTD is located in Gongyi, Henan province, which is one of the main abrasive and refractory production bases in China.

Before reuse, silica sand needs to be cleaned by means of screening systems and magnetic separators to segregate reusable sand from other wastes and to separate particles of varying sizes (Siddique and Noumowec, 2008). ... They are used for making shell, core, sand mold, and plaster mold for casting. Making them directly (instead of indirectly ...

Silica sand has long been used in core making, so switching to using the same aggregate throughout the casting process has made the process of managing foundry supplies easier. Silica sand is the most commonly used type of foundry sand.
