Ceramics Overview

Ceramics are inorganic materials that are both hard and brittle. Ceramics offer excellent thermal and electrical insulation properties. Examples of common ceramics include alumina (Al2O3), porcelain (Al2Si2O5(OH)), zirconia (ZrO2), earthenware, silicon carbide (SiC), and ceramic tile. Laser processing of ceramics is typically performed using a 10.6 or 9.3 micron CO2 laser with some ceramics also absorbing a 1.06 micron fiber laser wavelength. Laser cutting of thin film ceramic is also possible using a CO2 laser, producing a clean edge with little discoloration. Laser engraving of ceramics is achieved using a CO2 laser. This process results in a shallow textured depth that can be used to create intricate patterns and detailed images. Laser marking can be accomplished using a 1.06 micron fiber laser on certain ceramics, such as alumina, tungsten carbide (WC) and zirconia, to produce a dark, uniform surface mark.
