Refractory Specialty Casting Sands and Minerals

Silica

Volume-Stable Sand is Ideal for Casting.

If you require refractory sands and minerals, RSI can help with volume-stable sand like Core Pro and Shell Pro and other sands you may need.

Sand is used in casting, along with binders and resins. Volume-stable sand can withstand molten steel and other extreme materials, keeping the mold stable. Sand is especially helpful in electronic applications and other situations with tight tolerances. 

If your application calls for vitreous silica for castings, let us know. Our team can help you obtain specialty sands and minerals in most standard sizes. 

Metal, Glass, and Ceramics

Specialty sand like silica sand (composed of quartz and silicon dioxide) or alumina sand (composed of aluminum oxide) are well-known for their high-temperature resistance and thermal conductivity. Sand is often used in bricks and castables.

Whether you’re working in metal, glass, or ceramic, specialty sand is an important refractory product thanks to its various key properties. It has a high melting point, low thermal expansion rate, chemical inertia, and offers longevity and stability. 

Specialty raw sand can be used as a base material for refractory bricks, castables, and molds, contributing to the structural integrity of the application.

Sands engineered for high performance include the Core Pro and Shell Pro. These sands have been processed and treated to enhance their properties for specific foundry applications. Core Pro is designed for creating cores and cavities in castings, and Shell Pro is used for shell molding and precision casting.
