① The super-high service temperature: Maximum use temperature of zirconia fibers is up to
② The best thermal insulating property: The coefficient of thermal conductivity of zirconia is the lowest among all metal oxides.
③ The best corrosion resistance performance: The resistant ability against acid corrosion and alkaline corrosion of zirconia is remarkably superior to alumina and silica.
④ The lowest volatilization and non-pollution properties at high temperatures: The high-
temperature saturated vapor pressure of zirconia is the smallest among all metal
oxides, which makes zirconia fibers uneasily volatilize and have non-pollution at high
temperatures.

materials for single crystal growth furnaces,
② Zirconia fibers can be used as super-high temperature insulating materials, fence materials, ablation materials and satellite battery separation materials, finding their applications in spaceflight, military and nuclear power fields.
③ Zirconia fibers can be used as reinforcement materials for metal-matrix and ceramic-matrix composite materials, finding their applications in aviation and spaceflight fields. Especially when used for ablative and insulating functional composite materials, they will exert their unique advantages.
④ Zirconia fibers also can be used as high-temperature filtration materials and high-temperature reaction catalyst carriers, and so on.
① 30% or more energy saving;
