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.

Zirconium oxide ZrO2 nanoparticles application: 1. Refractory material . Zirconia fiber is a kind of polycrystalline mass refractory fiber material. Due to the high melting point, no oxidation ZrO2 material itself and other excellent high temperature properties, ZrO2 fiber is better than the alumina fiber, mullite fiber, aluminum silicate fiber, and other varieties of refractory fiber the use of higher temperature.Are a top refractory fiber material in the  international. 2. Ceramic material. Because the refractive index of a zirconium oxide, high melting point, corrosion resistance is strong, so used for ceramics raw material. Piezoelectric ceramic filter, speaker ultrasonic acoustic detector, etc. Ceramics for daily use (industrial ceramic glaze), precious metal smelting with zirconium tube and zirconium brick. Nano-sized zirconium oxide can also be used as a polishing agent, abrasive, piezoelectric ceramics, precision ceramics, ceramic glaze and high temperature pigment matrix material. 3. Gas turbine. Plasma spraying cubic zirconia thermal barrier coating application in aerospace and industrial gas turbine has great progress, within limits has been used in gas turbine turbine parts.Can significantly improve the durability of the high temperature parts, or allow to improve gas temperature or reduce cooling gas to the dosage and high temperature parts of constant temperature that can improve the efficiency of the engine.   For the further information of zro2 nanoparticles, please contact us freely.
