Description
A silicon nitride powder dedicated to structural ceramics, with α-phase content above 95 %, high sintering activity and stable batch-to-batch quality. It is used to produce wear-resistant silicon nitride parts where small wear-related dimensional error and long service life are critical.
Key features
- Wear-resistant, high hardness
- Suitable for high-speed cutting
- Small wear-related dimensional error
- Long service life
Applications
Silicon nitride cutting tools, nozzles and other wear-resistant structural parts.
