Alumina ceramics are mainly divided into fine Alumina ceramics and general Alumina ceramics. Many people do not know much about alumina ceramics. Alumina ceramics have many advantages. More and more products are processed by alumina ceramics. In industrial production, many enterprises need parts processed by alumina ceramics.Compared with parts made of other materials, alumina ceramics have better functions. How long is the life cycle of alumina ceramics?

   Alumina ceramics normally have a life span of about one year, but the existence of nitrifying bacteria may have a certain threat to the life of the ceramics itself. Although nitrifying bacteria exist and die, some corpses will wash away with the current, but some of them remain in the nitrifying bacteria voids, slowly accumulate in the back and plug the voids. The parasitic effect of the ceramic ring will gradually decrease, so it needs to be replaced regularly.

   After a period of use, you will find that the color of the ceramic turns yellow, because the impurities in the water have blocked the holes on the surface of the ceramic and can not be cleaned! 

   Generally speaking, there are many kinds of alumina ceramics. According to the different content of Al2O3, they can be divided into 99, 95, 90 and 85 ceramics. Sometimes, when the content of Al2O3 is 80% or 75%, they are also classified as ordinary alumina ceramics. Among them, 99 alumina ceramics are used to make high temperature crucibles, refractory furnace tubes and special wear-resistant materials, such as ceramic bearings, ceramic seals and water valve sheets; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant parts; 85 ceramics can be sealed with molybdenum, niobium, tantalum and other metals, and some of them can be used as electrical vacuum device devices, because talcum is often added into 85 ceramics, which improves electrical performance and mechanical strength. 

   Ceramics give the first impression that they are fragile, but alumina ceramics add special materials, so in terms of physical properties, it is much better than traditional ceramics. Qualified alumina ceramics have a high hardness level and will not be damaged under the conditions of extrusion and impact. 

   The service life of alumina ceramics is clear to everyone, but the specific service life of precision ceramics still needs to be based on the use environment.
