Silcarb continues to manufacture high-performance silicon carbide wear components for demanding industrial applications. Among these are nitride bonded and reaction bonded silicon carbide feed chambers and spigots, designed to withstand severe abrasion, corrosion, and high-velocity material flow in industrial processing systems.

These advanced ceramic components are commonly used in industries where equipment is exposed to aggressive slurry flows, abrasive particles, and continuous mechanical wear. Silicon carbide ceramics offer exceptional durability in such environments, making them a preferred material for wear-resistant applications.

Nitride Bonded Silicon Carbide for Wear Applications

Nitride bonded silicon carbide (NBSiC) is produced through a nitridation process where silicon reacts with nitrogen to form silicon nitride bonding phases within the silicon carbide structure. This bonding process results in a strong and thermally stable ceramic material.

Key properties include:

  • High mechanical strength
  • Excellent thermal shock resistance
  • Good corrosion resistance
  • Strong resistance to abrasive wear
  • Long operational service life

These characteristics make nitride bonded silicon carbide suitable for wear-intensive industrial components such as feed chambers and spigots.

Reaction Bonded Silicon Carbide Components

Reaction bonded silicon carbide (RBSIC), also known as silicon infiltrated silicon carbide (SiSiC), is another advanced ceramic material widely used in wear applications. It is produced by infiltrating molten silicon into a porous silicon carbide structure, creating a dense and highly durable ceramic.

Advantages of reaction bonded silicon carbide include:

  • Extremely high hardness
  • Excellent abrasion resistance
  • Low porosity structure
  • High corrosion resistance
  • Dimensional stability at elevated temperatures

These properties make RBSIC components ideal for abrasion-resistant industrial equipment.

Applications of Feed Chambers and Spigots

Silicon carbide feed chambers and spigots are widely used in equipment that handles abrasive materials or slurry systems.

Typical applications include:

  • hydrocyclone systems
  • mineral processing plants
  • slurry transport systems
  • mining operations
  • sand and aggregate processing
  • chemical processing plants

By protecting critical equipment surfaces from wear and erosion, silicon carbide components help extend equipment life and reduce maintenance downtime.
