Nano zirconium dioxide nanopowders used in refractory materials application:
Refractories: Because zirconia high temperature and anti-corrosion properties, it can resist the erosion of acidic or neutral melt, it is widely used as a special refractories, casting mouth, molds, and other high-temperature melt chute. It does not melt iron or steel wetted, so can be used as steel buckets, steel chute and so on.
Other application for zro2 nanopowders:
1. From a structural point of view, zirconium oxide because of its acidic and basic surface of the center, so it is an ideal base bifunctional acid catalytic material plays an important role in catalysis. Zirconium dioxide also has a unique phase transformation toughening, which makes high-zirconia ceramics not only strength, fracture toughness is also great. Meanwhile, zirconia having a high temperature oxygen ion conductivity, which is applied to the oxygen sensor.
2. Nano zirconia powder having unique properties, is an insulator at room temperature, and the electrically conductive at high temperatures toughening and sensitivity characteristics of the same rubber, ceramics, paint .
Household chemicals and other areas with a wide range of applications, can also be used in the manufacture of gas sensors, phosphors, pressure sensitive materials, piezoelectric materials, varistors, high-temperature fuel cells, high temperature optical components, efficient catalyst.
3. Electronic Ceramics: zirconia ceramics used in electronic piezoelectric major components (such as ignition devices, hearing aids, pickups, etc.), filter (used in televisions, tape recorders, a total power radio transceivers, etc.), ultrasound oscillator (for submarine sounds satisfied, fish finder and sounder), honey (for computer input signal power to identify tunes desk type computer, digital display watches and alarm clock, etc.) and high temperature conductors.
4. Functional Ceramics: zirconium dioxide in the main function of the ceramic gas sensor, a temperature sensor, a sound sensor, a pressure sensor, an acceleration sensor, automatic control systems and high-temperature high-tech solid dielectric and magnetic fuel cell electrodes fluid engine.
5. Structural Ceramics: No lubricating ball bearings and jet engines, internal combustion and turbine components can be used as space vehicles (such as putting, connecting rods, bearings, cylinder liners and piston cap, etc.). Zirconium dioxide produced by seals, valves, piping and other components in the chemical, metallurgy and other sectors have also been widely used.
