Silicon carbide powder for SiC ceramics
Silicon carbide powder is not only a common material for abrasives. It also plays an important role in the ceramic industry, especially in combustion appliances.
The burner has the advantages of a fast combustion rate, high thermal efficiency, and low pollutant emission, and is widely used in civil gas cookers, heaters, and other fields. Many factors affect the surface emissivity of the burner. Such as the composition of the surface material, temperature, surface roughness, and other factors. At present, the porous media materials used for the burner are ceramic materials and metal materials. The commonly used ceramic materials are silicon carbide, mullite, cordierite, etc.
The most remarkable feature of silicon carbide powder is as follows:
good thermal shock resistance
stable mechanical properties under high-temperature conditions
stable use under high-temperature conditions for a long time.
On the other hand, silicon carbide powder is suitable for big-size ceramic components. It won’t make deformation on big-size ceramics. Silicon carbide ceramics are widely used in applications such as:
preheater hanger in the cement industry.
high-temperature wear-resistant ceramic nozzle in steel and power plants
high-temperature transmission pipelines, etc.
The nozzle of the burner in the thermal power plant is basically made of silicon carbide material. The product has the characteristics of high-temperature resistance and wear resistance. It can be used together with the burner. The function is controlling the temperature difference in the cross-section of the kiln to make its temperature uniform.
The silicon carbide burner sleeve has the characteristics of rapid cooling resistance, heat resistance, wear resistance, oxidation resistance, high strength, no slag inclusion, no cracking, long service life, easy replacement, etc. It can effectively control the temperature balance in the kiln. It is an ideal burner for roller kilns, tunnel kilns, and shuttle kilns, and is applicable to industrial kilns such as ceramics, the chemical industry, metallurgy, etc.
