Ceradyne Ceralloy® 147-31E Sintered Reaction Bonded Silicon Nitride (Si3N4)  (discontinued **)
Categories: Ceramic; Nitride

Material Notes: Ceralloy® 147 Reaction Bonded Silicon Nitride (RBSN) is a high purity grade of silicon nitride. RBSN has excellent thermal shock resistance and outstanding compatibility with non-ferrous molten metals. This lower cost alternative to the fully dense silicon nitride grades can be manufactured to close tolerance without the need for expensive diamond grinding.

Features:

  • Impact Strength
  • Net Shape Fabrication

Applications:

  • Cutting Tools
  • Wear Components

Information provided by Ceradyne, Inc.

Ceradyne was acquired by 3M in 2012. The product line has been extensively renamed and reconfigured.
