the role of iron silicon nitride
1. Improve the high temperature resistance.
Ferrosilicon nitride has good high temperature resistance. When added to refractory, it can effectively improve the high temperature strength and stability of the material, making it difficult to ablate and melt in high temperature environment. This makes ferrosilicon nitride a common high-temperature refractory additive.
2. Improve oxidation resistance
When ferrosilicon nitride reacts with oxygen, it will generate SiO2, which will absorb some oxygen, thus achieving the effect of inhibiting excessive oxidation. In addition, iron silicon nitride can also prevent the crystal growth of metal atoms at high temperature, thus improving the oxidation resistance of materials.
3. Enhance corrosion resistance
Iron silicon nitride can interact with other oxides in refractory materials to form specific compounds, thus changing the composition and structure of the whole material and enhancing the corrosion resistance. This makes ferrosilicon nitride outstanding in some corrosive environments, such as the application in steel smelting and smelting.
the application of iron silicon nitride
Ferrosilicon nitride is widely used in refractories, which can be used in high temperature occasions such as high temperature kilns, stoves and bricks. For example, adding ferrosilicon nitride to the furnace wall of a steel plant can improve the high temperature resistance of the furnace wall and prolong its service life. In addition, ferrosilicon nitride can also be used to manufacture refractory products such as high-temperature alumina ceramics and grates.
Conclusion of silicon nitride
Ferrosilicon nitride is an excellent refractory additive, which can significantly improve the high-temperature strength and stability of materials and improve their oxidation resistance and corrosion resistance, so it is widely used in various high-temperature industries.
