Ceramic shot for finishing parts

Surface treatments by shot blasting and shot peening

Ceramic grit is a non-metallic abrasive of high hardness. Its unique characteristics make it an abrasive that offers great advantages over glass beads and provides a significant cost reduction in blasting and shot blasting processes that require high precision.

Ceramic abrasive is a non-metallic abrasive whose main compound is zirconium oxide. By means of a fusion process, they are obtained in the form of spherical beads that are classified according to their size. Ceramic shot is iron-free and extremely hard thanks to a vitreous silicon phase that gives it high hardness and toughness.

As a result, it offers a number of advantages over the glass microsphere, which is its natural competitor:

  • It provides greater durability, more than 60 cycles compared to glass microspheres.
  • More homogeneous finishes.
  • Considerable reduction in consumption due to its lower breakage rate.
  • It reduces cycle times compared to glass beads and has lower wear. It is also a guarantee when treating delicate parts with sharp edges.
  • As it is iron-free, it does not produce oxidation problems or contaminants.

Due to its specific weight, hardness and toughness, ceramic grit is a highly valued abrasive.


Ceramic grit is an abrasive composed mainly of zirconium. For its production, the raw material granules are transformed into shot (in the form of small spherical balls) after a crushing and mixing process.

This shot is supplied in different sizes, classified according to grain size, to suit the specific needs of each application.

The production process is subject to strict quality controls, in which the grain size, shape, composition and strength of the ceramic shot are monitored.

We have standard ceramic shot and ceramic shot produced under military regulations.


As mentioned above, ceramic shot has the same uses as glass beads.

Its great advantage is that, due to the absence of iron and its great hardness, this ceramic abrasive can be applied with great results in satin surface finishes on stainless steel, bronze, brass, aluminium, magnesium, etc.

Ceramic grit is a reusable abrasive, which reduces the economic cost in processes such as shot blasting, shaping, cleaning, cleaning, polishing, polishing, lapping, or shot peening.

It is a shot blast widely used in sectors such as aeronautics, medical-surgical and boilermaking of stainless materials.

These are some of the most frequent applications of ceramic shot:

  • Satin parts and matte effects.
  • Final finishing of parts.
  • Cleaning of stainless materials.
  • Weld pickling.
  • Cleaning of metal parts.
  • Cleaning of delicate materials such as molds, dies, dies, etc.
  • Repair defects in the part.
  • Preparation of parts for other treatments.
  • Elimination of surface tensions.
  • Blasting of aluminum parts.

Instructions for use

Ceramic grit is ideal for surface treatments by blasting, both by suction and pressure blasting, and by shot blasting, although in the latter case it is limited to shot blasting by turbines.

These are some of the technologies with which ceramic blasting can be applied with great results:

  • Manual suction and pressure blasting booths.
  • Portable sandblasters.
  • Shot blasting rooms and blasting rooms.
  • Shot blasting with compressed air gun and turbine equipment.
  • Automatic shot blasting equipment.
