Compared with ordinary types of ceramic fiber cotton, zirconium-containing ceramic fiber cotton has many obvious advantages, mainly in the following aspects:

I. Higher high temperature resistance

Zirconium-containing ceramic fiber cotton has higher service temperature and can withstand extremely high temperature environment. The service temperature of ordinary ceramic fiber cotton is usually around 1000℃, while the service temperature of zirconium-containing ceramic fiber cotton can reach 1350℃, which makes it more advantageous in high-temperature industrial application.

II. Lower linear shrinkage

In high temperature environment, the linear shrinkage of zirconium-containing ceramic fiber cotton is lower. For example, at 1350℃, the linear shrinkage of zirconium-containing ceramic fiber cotton is -3%, while that of ordinary ceramic fiber cotton is -4% at 1000℃. This means that the zirconium-containing ceramic fiber cotton can maintain a more stable size and shape at high temperature.

III. Better thermal insulation performance

Zirconium-containing ceramic fiber cotton has lower thermal conductivity and better thermal insulation effect. For example, at 600℃, the thermal conductivity of zirconium-containing ceramic fiber cotton is 0.176 w/m k, while that of ordinary ceramic fiber cotton reaches 0.176 w/m k at 800℃. This shows that zirconium-containing ceramic fiber cotton can maintain good thermal insulation performance at low temperature.

IV. Higher tensile strength

Zirconium-containing ceramic fiber cotton has higher tensile strength and can withstand greater mechanical stress. Its tensile strength can reach 21 MPa. Compared with ordinary ceramic fiber cotton, it has stronger mechanical properties and is not easy to be damaged.

V. Good chemical stability

Zirconium-containing ceramic fiber cotton has stronger acid and alkali corrosion resistance and is suitable for various chemical environments. Its chemical stability makes it perform well in high-temperature equipment in chemical and petrochemical industries, and it can resist the erosion of many chemicals.

VI. Sound absorption and sound insulation performance

The fiber structure of zirconium-containing ceramic fiber cotton is uniform, which can effectively reduce the sound transmission and has good sound absorption and sound insulation effect. This makes it perform well in occasions where sound insulation and heat insulation are needed.

VII. Environmental protection and non-toxic

The main raw material of zirconium-containing ceramic fiber cotton is inorganic, which is non-toxic and harmless, and has no adverse effects on the environment and human health.

VIII. Construction convenience

Zirconium-containing ceramic fiber cotton is soft and convenient for construction operation. It can be torn thin or into small pieces at will, which is suitable for complex construction environment.

IX. Summary

Zirconium-containing ceramic fiber cotton has obvious advantages over ordinary ceramic fiber cotton because of its higher high temperature resistance, lower linear shrinkage, better thermal insulation performance, higher tensile strength, good chemical stability and sound absorption and sound insulation performance. These characteristics make it more competitive in the field of high-temperature industry, especially for high-temperature equipment in metallurgy, chemical industry, electric power and other industries.
