Zirconia ceramics have many advantages, especially the optical fiber connectors and patch cords used in the production of optical fiber networks are widely used in optical fiber networks, and they are also optical passive devices in large demand. There are also the core parts of the single-mode multi-mode movable optical fiber connector, the main component of which is the zirconia ceramic sleeve (that is, the connector precision needle), which uses stable tetragonal zirconia powder. A brief analysis of the use of zirconia ceramics by grinding, let's take a look at it together.
