Saint-Gobain’s #190 is a hollow, spherical alumina thermal spray powder designed for high purity applications. The 99.9+% pure material is white alpha alumina with particle sizes from 10-30 micron as controlled by Microtrac. The hollow-sphere materials spray with high deposit efficiency and smooth delivery to the plasma with high flow rates. Saint-Gobain suggests using #190 for applications requiring high dielectric strength, such as ESC. The #190 also provides very good wear resistance.
Saint-Gobain’s #199 Alumina is a spherical alumina thermal spray powder designed for high purity applications. This 99.9+% pure material is based on sol-gel feeds and is available with particle sizes from 10-75 microns as controlled by Microtrac. Saint-Gobain suggests using #199 for electronic applications like ESC or where high dielectric strength is required. The #199 can also be used for applications requiring wear resistance.
