The surface preparation industry is focused on cleaning or altering surfaces of
materials through the use of abrasive blasting or other means. Abrasive blasting
involves impacting the target materials with abrasive media at high velocities.
The high hardness and wear resistance of silicon nitride provides the material of
choice for blast nozzle liners.
Sand Blast Nozzle Liners
Ceradyne manufactures sand blast nozzle liners for use in the surface preparation
industry. Ceradyne offers a line of “long venturi” liners from Ceralloy® 147-31N
grade of silicon nitride.
These make use of silicon nitride’s abrasive wear characteristics that are superior
to other materials such as aluminum oxide and tungsten carbide.
Sand blast nozzle liners are available from stock, and custom designs are available
upon request.
