3M™ Fused Silica Grains are among the highest quality available on the market. At 99.7% purity, these flours are fireproof, sanitary, UV-resistant, and scratchproof. 3M fused silica grains are optimized for consistency from batch to batch, to help you produce components with a high degree of dimensional accuracy.

A Pure Product
3M™ Fused Silica Grains (PDF, 183.1 Kb) are high-purity ceramic sands used in the investment casting shelling process, as well as refractory applications. Our revolutionary furnace design helps prevent the raw silica sand from becoming contaminated during processing — resulting in a finished product that is 99.7% pure, while increasing productivity tenfold over conventional furnaces.

Custom Designed for Your Application
3M fused silica grains are available in both standard and custom particle sizes and distributions, and our experts will work with you to optimize your application. Because each foundry has different requirements, these fused silica grains are engineered with built-in flexibility and can be adjusted for specific application needs. 3M fused silica grains are available in 55 lbs. (25 kg) paper bags or 2,200 lbs. (1,000 kg) tote sacks.
