Christy Minerals Fused Silica

Christy Minerals is pleased to announce the addition of the 3M Fused Silica business, a part of their Advanced Materials Division. With the acquisition of the Fused Silica business from 3M in 2025 we have added high quality Fused Silica to our product portfolio. Located in Midway, TN this facility produces Fused Silica products optimized for purity and consistency.

From gas turbines to golf clubs, high-precision metal parts require accuracy and consistency at every stage of the manufacturing process. Engineered for use in investment casting foundries, Christy Minerals Fused Silica products include grains, flours, blends, and advanced shell systems to help meet these exacting requirements – and create parts that fit the mold every time.

Christy Minerals Fused Silica products are optimized for purty and consistency. Our revolutionary furnace design helps prevent raw silica sand from becoming contaminated during processing, resulting in a product that is 99.7% pure. Christy Minerals Fused Silica products are optimized for batch-to-batch consistency for a more accurate mold and faster overall production.

Christy Minerals Fused Silica products are used in the production of close-tolerance components for aerospace, automotive, construction, energy and many other industries. Our portfolio also includes fused silica castables and shapes that are well suited for use where high temperatures, thermal shock resistance and low thermal expansion are critical – including photovoltaic casting, glass melting, titanium processing, and other metal forming operations.
