Ceralloy® 147 Reaction Bonded Silicon Nitride (RBSN) is a high purity grade of silicon nitride having a density of approximately 70-80% of theoretical. 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. Applications: Industrial applications, electrical insulators, sputtering targets. Information provided by Ceradyne Company Ceradyne was acquired by 3M in 2012. The product line has been extensively renamed and reconfigured. |
