Product brief description:
Silicon Carbide Ceramic Nozzle Introduction:
Silicon carbide nozzle is a nozzle component made of silicon carbide (SiC) material through compression molding, injection molding, or more precise reaction sintering (RSiC), pressureless sintering (SSiC) and other processes. Its main function is to spray liquid or slurry at a specific flow rate, shape, speed, and direction.
Silicon Carbide Ceramic Features:
- * good wear-resistance property
- * corrosion resistance
- * high temperature resistance
- * high hardness
We can provide you all kinds of high performance nozzles, such as spray nozzles, oil nozzles, blasting nozzles and so on. With high speed to wash,

Silicon carbide ceramic nozzle advantages
- ① Excellent wear resistance
Silicon carbide has extremely high hardness, second only to diamond and cubic boron nitride.
When spraying media containing solid particles such as slurry, dust, catalysts, etc., the wear rate is much lower than that of metal, plastic, and even other ceramic nozzles, and the service life can be extended several times to tens of times. This is one of its most prominent advantages.
- ② Excellent corrosion resistance
Silicon carbide can withstand the corrosion of most acids, bases, and salts.
Suitable for spraying various corrosive chemical media, such as acidic wastewater, strong alkaline cleaning solutions, corrosive gases, etc., without rusting or chemical degradation.
- ③ Excellent high temperature stability and thermal shock resistance
Silicon carbide can maintain its strength at high temperatures above 1600 ° C, with a low coefficient of thermal expansion and good thermal conductivity.
- ④ High temperature resistance: It can work stably for a long time in environments such as high-temperature furnaces and burners.
- ⑤ Thermal shock resistance: able to withstand drastic temperature changes without cracking, extremely reliable in scenarios such as cold start-up or intermittent operation.
- ⑥ High mechanical strength
Sintered silicon carbide has high compressive and bending strength.
The nozzle structure is sturdy and not easily damaged due to installation pressure, medium pressure, or accidental impact.
- ⑦ Good antioxidant properties
In high-temperature air, a dense layer of silicon dioxide (SiO ₂) protective film forms on the surface of silicon carbide, preventing further oxidation.
Silicon carbide nozzle is a high-performance industrial component that achieves the optimal balance between wear resistance, corrosion resistance, high temperature resistance, and thermal shock resistance, solving numerous nozzle life and reliability issues under harsh working conditions. Although its initial procurement cost is relatively high, due to its long service life and stable performance, its comprehensive usage cost is often lower in situations where frequent nozzle replacement is required, making it an ideal choice for improving production efficiency and equipment reliability.
