Silicon Carbide Burner Nozzle Tech Ceramic
PRODUCT DESCRIPTION
Silicon nitride bonded silicon carbide burner nozzle, with its characteristics of ultra-high temperature, corrosion resistance, and long service life, NSiC burner nozzle has become an ideal choice for harsh working conditions, especially suitable for high-temperature corrosive environments，high purity processes, efficient combustion system.
1. Silicon nitride bonded silicon carbide burner nozzle has a hard texture, with a Mohs hardness of about 9. Silicon nitride combined with silicon carbide belongs to ultra-high hardness materials in non-metallic materials.
2. Silicon nitride bonded silicon carbide burner nozzle not only has high strength at room temperature, but also maintains almost the same strength and hardness as room temperature at high temperatures of 1200-1400 ℃, and can work for a long time at 1450 ℃.
3. Silicon nitride combined with silicon carbide burner material has a low coefficient of thermal expansion, higher thermal conductivity compared to silicon carbide and other products, is less prone to thermal stress, has good thermal shock stability, and has a long service life. Strong high-temperature creep resistance, corrosion resistance, extreme cold and heat resistance, oxidation resistance, easy to produce products with high dimensional accuracy that meet the requirements.
4. Silicon nitride combined with silicon carbide material does not infiltrate with non-ferrous metals, and its performance is significantly better than oxide ceramics. It also has good insulation properties and is widely used in vulnerable parts such as smelting furnaces and burner areas in non-ferrous smelting industries such as lead, zinc, aluminum, and copper.
CORE CHARACTERISTICS
Silicon nitride bonded silicon carbide (NSiC) burner nozzle:
High temperature resistance: Long term use temperature up to 1450 ° C.
Thermal shock stability: low coefficient of thermal expansion, resistant to rapid cooling and heating without cracking.
Corrosion resistance: resistant to acid/alkali/molten salt corrosion (except for strong oxidizing acids), suitable for corrosive atmospheres .
High thermal conductivity: high thermal conductivity, high combustion efficiency, uniform temperature distribution and density.
Lightweight: over 30% lighter than metal burners.
