Specifications
Si3N4 Ceramic Silicon Nitride Tube/INNOVACERA
Material Description
| Silicon Nitride (Si3N4) Description: |
|
Si3N4 ceramic is continuous and robust network structure because of its basic structural unit [SiN4]
tetrahedral construction.So it has the chacteriastics: |
|
? Low coefficient of thermal expansion, ? High thermal conductivity ? Excellent thermal shock resistance
? Low density |
|
Especially Hot sintered silicon nitride,But if it is used of more than 1200 ℃, it becomes broken then to reduce its strength, fatigue damage will be appeared at more than1450 ℃, So Si3N4 using temperature generally does not exceed 1300 ℃. Due to the low Si3N4's high strength, low density, high temperature and other properties,it is very appropriate to replace steel in some industry. |
