Ceramic sand can be used for shot peening. A large number of shot shots are sprayed on the surface of the part. The violent impact will cause extremely strong plastic deformation on the surface of the metal part, resulting in a certain thickness of cold work hardening layer on the surface of the part, called the surface strengthening layer. This strengthening layer will significantly improve the fatigue strength of parts under high temperature and high humidity.

Zirconium silicate shot peening is widely used due to its special chemical structure and density characteristics (larger than glass bead and smaller than steel shot). In the military field, the ceramic sand is used for the surface strengthening treatment of precision casting parts such as turbine blades and shafts of aircraft, ordnance, and various spring gear hydraulic parts to eliminate internal stress.

In the civil field, ceramic sand is used for tool cleaning, surface finishing and surface pretreatment of titanium alloy and stainless steel workpieces and products (stainless steel tableware, kitchen utensils), textile machinery parts, punching and forging abrasive tools, mechanical abrasive tools, medical devices and other metal products, as well as deoxidizing, rust removal, burring, strengthening and polishing. Cleaning of tools and abrasives for glass processing, tire manufacturing and plastic molding.
