#190 Series High-Purity Spherical Alumina Thermal Spray Powder

Saint-Gobain High Purity Spherical Alumina is produced in a variety of particle size distributions. The spherical shape provides improved flow characteristics for a more stable and predictable coating process. They produce dense coatings with good resistance to abrasion, erosion, sliding wear, and oxidation.

The high purity (99.9+%) and finer sizes are well suited for dielectric applications like ESC’s (electrostatic chucks) or corona treater rollers. The low levels of impurities also maximize the coating performance in many demanding applications.
