Silicon Nitride Ceramic - Silicon Nitride Ceramics ...
2021-3-18 · Si3N4 has good impact resistance due to its low thermal expansion coefficient and high thermal conductivity.Hot pressing sintering of silicon nitride heating to l000 ℃ after into the cold water will not break.In the not too high a temperature, Si3N4 has high strength and impact resistance, but in more than 1200 ℃ can grow along with the use of time and failure, reduce its strength, above 1450 ℃ …
