Abrasive Blasting Nozzles and FGD Nozzles

Saint Gobain Specialty Ceramics' products allow customers to solve tough

The extreme hardness of sintered silicon carbide and hot pressed boron carbide makes these materials excellent choices for nozzles and wear pads in high wear applications.


Hexoloy® SA SiC and Norbide® B4C nozzles outlast tungsten carbide and demonstrate proven performance in abrasive blasting and atomization applications.


Silit® SKG SiSiC and Hexoloy® SA SiC spiral nozzles are frequently used for flue gas desulfurization (FGD) in power plants.


What advantages does boron carbide offer over silicon carbide?

Boron carbide is lighter and harder than silicon carbide.

What advantages do silicon carbide and boron carbide nozzles have over tungsten carbide?

Both silicon carbide and boron carbide are lighter materials than tungsten carbide, while also offering superior hardness. These key factors enable easier nozzle handling and longer service life.

What are the advantages of using silicon carbide nozzles in power plants?

Hexoloy® SiSiC and Silit® SiSiC offer excellent chemical corrosion resistance and abrasion resistance. This makes these materials ideally suited to the harsh environment typically found in flue gas desulfurization units in power plants.
