Why do silicon nitride ceramics with good hot corrosion performance stand out?
Silicon nitride ceramics (Si ∝ N ₄) exhibit excellent performance in high-temperature corrosive environments due to their unique crystal structure and chemical stability

1. Excellent heat and corrosion resistance
   At high temperatures of up to 1400 ° C, silicon nitride can still maintain excellent oxidation and corrosion resistance, especially in environments with corrosive media such as sulfur, chlorine, and sodium. Its performance far exceeds that of most metals and oxide ceramics.
2. Combination of high strength and high toughness
   Silicon nitride ceramics prepared using advanced sintering technology have a bending strength of 800-1000 MPa, high fracture toughness, good thermal shock resistance, and can withstand rapid cooling and heating conditions.
3. Excellent chemical inertness
   It has strong resistance to most acids, alkalis, and metal molten salts, is not prone to chemical corrosion, and extends the service life of components in chemical reactors, melting furnaces, and other equipment.

Typical application scenarios: What practical problems are solved?

1. Aerospace field
   Used for turbine engine blades, combustion chamber components, etc., to resist high-temperature gas corrosion, improve engine efficiency and lifespan.
2. Chemical and metallurgical industries
   As a furnace lining, crucible, conveying pipeline, etc., it can work stably in highly corrosive molten salt and metal liquid environments, reducing the frequency of equipment shutdown and replacement.
3. Semiconductor manufacturing equipment
   Used for wafer carriers, heat treatment fixtures, etc., it does not produce pollution in high-purity and high-temperature processes and is resistant to plasma corrosion.
4. In the field of new energy and environmental protection
   Applied to components of garbage incinerators, fuel cell modules, etc., it resists acidic flue gas corrosion and improves system durability.
