– Injection molding for intricate geometries.
– Tape casting or extrusion for thin sheets or tubes.

Compaction under controlled pressure is critical to avoid defects like pores or density gradients.

Key Actions:
– Request detailed forming process specifications and defect rate records.
– For high-spec applications, ask about green-body inspection technologies (e.g., ultrasonic, X-ray).

4. Sintering and Densification
Formed “green” bodies undergo sintering, subjected to temperatures of 1600–1800°C in nitrogen-rich or inert atmospheres. Two main pathways:
– Pressureless sintering: Simpler, but may yield slightly lower densities.
– Hot isostatic pressing (HIP): Applies simultaneous heat and pressure, ensuring near-theoretical density and enhanced mechanical properties.

Sintering schedule (temperature/time profile) profoundly influences grain size, phase composition, and final strength.

Key Actions:
– For critical uses, specify HIP or advanced sintering as a requirement.
– Review sintering logs and temperature uniformity data.

5. Finishing and Machining
Post-sintering, parts may need precise grinding, lapping, or polishing. Since silicon nitride is extremely hard, specialized diamond tooling is required to achieve close tolerances and surface finishes.

Key Actions:
