Ceramic shot and grit are excellent abrasive blast medias for blasting applications which require a clean finish for air blast, wheel blast or wet blasting. Abrasive Products represents St. Gobain and their ceramic bead and grit products, Zirblast, Zirshot and Zirgrit. Ceramic shot is spherical in shape. Ceramic grit is angular. Ceramic shot is typically used for cleaning applications and often shot peening processes. Ceramic grit would be used in applications in which etching the workpiece surface or removing a tough contaminant is the ultimate goal.
These products are often referred to as zirconia beads or zircon beads or zirconia or zircon grit due to their high percentage of zirconia. Unlike glass bead, ceramic bead is very resilient, tough, and is highly elastic. Ceramic bead tends not to fracture nearly as quickly as glass bead. These products have virtually zero iron content so they are good products to consider where ferrous contamination is of concern for your workpiece.
