What Are The Reasons For The Discoloration Of Alumina Ceramics


What Are The Reasons For The Discoloration Of Alumina Ceramics

Alumina ceramics is actually a kind of ceramic structure formed by adding alumina during the production of ceramics, so it will appear white, but if the raw materials contain impurities, the alumina ceramics will turn yellow or gray, but the vast majority Some alumina ceramic products are basically white, and alumina ceramics are basically white like alumina ceramics. After our ceramic products have been used for a long time, they will turn from white castings to light yellow, so what are the reasons for the discoloration of alumina ceramics?

The technical talents in the production process of ceramic products mainly produce various precision ceramic products of alumina ceramics and alumina ceramic materials. The precision ceramic products produced are widely used in measuring tools, pump valves, lithium batteries, semiconductors, electronic appliances, smart wear, Laser, petroleum, chemical, medical, food, photovoltaic, military, aerospace and other industries.

What Are The Main Reasons Why White Alumina Ceramics Gradually Turn Pale Yellow


  • First of all: the reason why alumina ceramics slowly turns from white to light yellow is that after sunlight exposure, the internal composition of alumina ceramics will slowly change, and this change is irreversible. Therefore, the alumina ceramic will slowly transform from a white state to a pale yellow state.
  • Secondly, there is another reason for the discoloration of ceramic alumina ceramics, which may be the deliquescence of alumina ceramics, resulting in chemical reactions between hydrated aluminas. In fact, not only ceramic products have this characteristic, but other materials also have this characteristic, so we can only overcome the phenomenon of discoloration of alumina ceramics by minimizing the influence of external factors.

In addition to this, in addition to clarifying the reasons behind the discoloration of alumina ceramics, it is also necessary to master some basic principles of using it to make shaft cores to ensure that the products made of alumina ceramics meet the requirements of the market. Products that cannot keep alumina ceramics used normally.

At the same time, we all consider that the alumina material is relatively special, so we should be more cautious when designing the alumina ceramic shaft core to reduce unnecessary damage to alumina ceramic products. The main content involved mainly includes the type, size and position of the installed parts, the fixing method of the parts, the nature, direction, size and distribution of the load; the type and size of the alumina ceramic bearing; the blank, manufacture and distribution of the alumina ceramic shaft. Assembly process, installation and transportation; deformation of the shaft and a series of factors.

What are the reasons for the discoloration of alumina ceramics? I will share with you here. The main reason for the discoloration of ceramic alumina ceramics is that after prolonged sunlight exposure, alumina will have a white state and slowly turn into a light yellow state. , If we want to avoid discoloration of alumina ceramics, we can overcome the phenomenon of discoloration of alumina ceramics by minimizing the influence of external factors.
