I believe everyone knows that zirconia ceramics mainly contain oxides composed of oxygen and zirconium elements. Therefore, zirconia ceramics will contain a certain amount of oxygen. The amount of oxygen content will directly determine the effectiveness of zirconia ceramics to a certain extent. Therefore, in order to better ensure the effectiveness of zirconia ceramics, we need to test the oxygen content in zirconia ceramics. Do you know how to test the oxygen content in zirconia ceramics? Below, the editor will introduce to you:

Method for testing the oxygen content in zirconia ceramics:

1. To test the oxygen content in zirconia ceramics, we can use an oxygen content analyzer to quickly and effectively comprehensively detect zirconia ceramics, making it an ideal analysis device for detecting the oxygen content of zirconia ceramics

2. When zirconia ceramics are heated to a certain temperature, the logarithm of the ratio of oxygen concentration in the measurement gas to the reference gas is directly proportional to the electromotive force between the two electrode plates. Therefore, as long as the magnitude of the electromotive force of zirconia ceramics is measured, the oxygen content in the measured gas can be determined

3. Zirconia ceramics, as a solid electrolyte, have the characteristic of transferring heterooxygenic ions at high temperatures. Therefore, porous platinum electrodes are now installed on both sides of zirconia ceramics. One platinum electrode is in full contact with a gas with a known oxygen content, and the other platinum electrode is in full contact with the oxygen containing body on the waiting side. When the oxygen concentration in the gas on both sides is different, the oxygen molecules on the high concentration side obtain electrons from the platinum electrode and become oxygen ions, making the platinum electrode the cathode of the battery. Oxygen ions pass through the zirconia ceramic dielectric and reach the low concentration side, losing electrons to the platinum electrode. They become oxygen, making the platinum electrode the anode of the battery, forming a concentration cell with zirconia as the electrolyte. An electromotive force is generated between the two electrode plates. When zirconia ceramics are heated to a certain temperature, the logarithm of the ratio of oxygen concentration in the measurement gas to the reference gas is directly proportional to the electromotive force between the two electrode plates. Therefore, as long as the magnitude of the electromotive force is measured, the oxygen content in the measured gas can be determined.

In summary, it is a method for testing the oxygen content in zirconia ceramics. Zirconia ceramics have different properties due to their different oxygen content. It is appropriate to achieve a certain ratio of oxygen and zirconium elements. Zirconia ceramics use standard proportions to process high concentration zirconia ceramics, thereby obtaining various ceramic parts.
