  Yttria Stabilized Zirconia powder(8YSZ)  oxygen measuring device used in coal-fired power plants


    An important task of coal-fired power plants is optimize combustion,namely,to improve the boiler efficiency, reduce the coal consumption,  energy conservation. which requires timely and accurate on-line monitoring to the combustion parameters. flue gas oxygen content online detection technology is based on the principle of zirconia solid electrolyte oxygen measurement, analyze various the external and internal factors that affect the oxygen measurement, it is concluded what is the do's and don'ts in the process of measurement of the zirconium oxide oxygen measuring device.Zirconia sensor constant work temperature control is the key measurement technology for improving the accuracy of measurement.


    The probe of zirconia measurement oxygen sensor is a kind of zirconia solid electrolyte (ZRO2 belongs to anionic solid electrolyte). At room temperature it is monoclinic crystal, when the temperature increases to 1150 degrees, the crystals translates into cubic crystal, while produce about 7% of the volume contraction. When the temperature falls, and become a monoclinic crystal.If the repeated heating and cooling, ZRO2 will break, so pure ZRO2 cannot serve as measuring element. If ZRO2 add a certain amount of yttrium oxide Y2O3 as stabilizing agent, after high temperature roasting, it will translate into stable zirconia materials.


    Yttria Stabilized Zirconia(YSZ)  oxygen measuring device is also called oxygen sensor, for the special appliacation ZRO2/Zirconia added Y2O3/Yttria is namely 8YSZ(stock#:U708) by HW NANO, the powder properties by shown the following table.

In yttrium-added zirconium oxide, yttrium oxide is used as a stabilizer, and this material is mainly a tetragonal structure. It has the highest flexural strength of all zirconia materials, especially when sintered and pressed. Yttrium stabilized zirconia has fine grains and is suitable for use in cutting tools due to its high wear resistance. It is used to cut a very sharp corner part. The excellent crystal grains make the produced ceramics dense, without many pores, and have excellent mechanical strength, corrosion resistance, impact toughness, thermal shock resistance and extremely low thermal conductivity. Because of these characteristics, yttrium stabilized zirconia is mainly used in wear-resistant parts, cutting tools and thermal barrier coatings.
