The ceramic micro-spheres are made up of zirconium (ZrO2) immersed in a glassy matrix.
Chemically inert and with spherical shape, they generate a good surface finishing creating an effect which is similar to the satiny one.
The main features of ceramic micro-spheres are:
- high hardness to obtain the best sandblasting results.
- high toughness and long life of the abrasive.
- scarce dust formation during the sandblasting process.
- reduced contamination of the sandblasted surface
Uses and Advantages
They are suitable to sandblast most of the metallic surfaces (steel, stainless steel, aluminium, brass, etc.).
Having a relatively low specific weight they are used with free cast sandblasting machines and in pressure or suction pressure compressed-air sandblasting cabins but they may also be used – if the sandblasting is opportunely adjusted – also on turbine shotblasting machines.
