利用氧化锆的氧离子导电性而发展起来的氧量测试技术,在机械、冶金、电力、化工等方面受到了广泛的注意。由于 ZrO_2氧浓差电池可以在高温下直接使用(例如,可在600～1400℃使用),这就为现场测试许多高温过程的气氛开辟了途径。因为是现场测试,因而避免了传统方法(例如:磁氧、CO_2计、露点仪等)的取样问题以及由取样过程而产生的气体成份变化及水蒸汽凝结等所带来的失真。同时,电池处于高温状态,反应很快,这就为过程的自动控制带来了很大的方便。热处理中证明用此法控制碳势比用 CO_2仪要稳定。电池的对数输出使测量范围可以很宽。由于这些优越的性能,因而近些年来美、英、苏、日、德等十多个国家都在进行固体电解质氧浓差电池方面的研究或应用工作。测气体氧含量有两个方面是特别引人注目的。一是气体氧含量测试可用来提高过程的效率,如燃烧过程,以达到节约燃料、减少污染的目的;二是氧量监测可以控制工艺过程中气氛的合理成份,如退火炉气氛监测,以保证产品质量,节约气体、节约金属等。
The use of zirconium oxide oxygen ion conductivity and the development of the oxygen testing technology, in machinery, metallurgy, electric power, chemical industry, has received widespread attention. Since ZrO 2 oxygen concentration cells can be used directly at high temperatures (for example, at 600-1400 ° C), this opens the door to testing the atmosphere in many high-temperature processes. Because it is a field test, sampling problems of traditional methods (such as magnetic oxygen, CO 2 meter, dew point meter, etc.) and variations of gas composition and water vapor condensation caused by the sampling process are avoided. At the same time, the battery is at a high temperature, the reaction is fast, which brings great convenience for the process of automatic control. Heat treatment proved that using this method to control the carbon potential than the CO_2 instrument to be stable. The logarithmic output of the battery allows the measurement range to be wide. Due to these superior properties, more than ten countries such as the United States, Britain, the Soviet Union, Japan, Germany and other countries are conducting research or application work on solid electrolyte oxygen concentration batteries in recent years. There are two aspects of measuring oxygen content of the gas is particularly compelling. First, the gas oxygen content test can be used to improve the efficiency of the process, such as the combustion process, in order to achieve fuel savings and reduce pollution purposes; Second, oxygen monitoring can control the atmosphere in the process of rational composition, such as annealing furnace atmosphere monitoring to ensure Product quality, save gas, save the metal and so on.
