60-80nm Fireproof Material Zirconium Oxide Nanopowders

zirconium oxide nanopowders information:

1.Odourless tasteless white crystals, soluble in water, hydrochloric acid and dilute sulphuric acid.

2.Chemical inertness and high melting point, high resistivity, high refractive index and the properties of low thermal expansion coefficient.

Zirconium oxide nanopowders 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.
