ジルコニアセラミックス are primarily composed of oxides of oxygen and zirconium. Zirconia ceramics typically contain a certain amount of oxygen, and this oxygen content directly determines their performance. Therefore, accurate detection of this component is essential. So how do we test the oxygen content in zirconia ceramics? Let’s take a look:

For this purpose, a specialized oxygen content analyzer has been developed, which can quickly and effectively detect the oxygen content in zirconia ceramics. With its simple structure, good qualitative analysis, high sensitivity, and fast response speed, the oxygen content analyzer has become an ideal analytical device for detecting the oxygen content in zirconia ceramics and is currently widely used. It is designed based on the concentration gradient principle in electrochemistry.

Oxygen molecules gain electrons from the platinum electrode, becoming oxygen ions, making the platinum electrode the cathode of the battery.

Oxygen ions travel through the zirconia ceramic dielectric to the side with lower concentration, losing electrons and donating them to the platinum electrode, becoming oxygen molecules and making the platinum electrode the anode. This forms a concentration cell with zirconia as the electrolyte, generating an electromotive force (EMF) between the two plates. When the zirconia ceramic is heated to a certain temperature, the logarithm of the ratio of oxygen concentration in the measuring gas to that in the reference gas is proportional to the EMF between the two plates. Therefore, by measuring the magnitude of the EMF, the oxygen content in the measured gas can be determined.

This device can analyze not only the oxygen purity in zirconia ceramic but also trace amounts of oxygen in high-purity hydrogen and high-purity nitrogen. This can be achieved simply by adjusting the analyzer to the appropriate range based on the trace oxygen content in the gas.

Zirconia ceramics exhibit varying properties due to differences in oxygen content. A specific ratio of oxygen to zirconium is necessary for optimal performance. Zirconia ceramics are processed using a standard ratio of high-concentration zirconium ceramics to produce various ceramic components, such as ceramic rods, ceramic plates, and ceramic rings.
