Mineral Slag is an efficient blasting abrasive manufactured from chrome slag raw materials. The end product is clean, dry, perfectly-graded abrasives for optimum performance.
AGT60 and AGT90 are able to produce a surface profile that varies from 40 – 110 microns.
Expendable abrasive ideal for site and steel blasting applications.

Amorphous silica is, by definition, the non-crystalline form of silica (SiO₂). Crystalline silica has an orderly lattice structure, while amorphous silica is unstructured, so the two differ not only physically but also in how they affect health. The form linked to silicosis is crystalline silica. The silica in our mineral slag is amorphous, with less than 1% free crystalline silica.
