Precautions for Using Silicon Nitride Ceramics

 
At a not-too-high temperature, silicon nitride has high strength and impact resistance, but above 1200℃ it will break with the increase of use time, reducing its strength. Above 1450℃ it is more prone to fatigue damage, so the use temperature of silicon nitride generally does not exceed 1300℃.
