How much do you know about alumina ceramics?
First of all, we want to introduce the crystal types of alumina. Alumina has three types of crystals, ionic crystals and atomic crystals, and one is somewhere in between. So, what does it have to do with alumina ceramics? Because there are atomic crystals in the crystals of alumina ceramics, the atomic crystals have the effect of not being afraid of alkalis and acids. Other alumina crystals, such as ionic crystals, will be converted into acid and alkali.
alumina ceramics are widely used. Because of the superior performance of alumina ceramics, it is more and more widely used in daily life. Generally, they are used in daily necessities or special properties. of. However, regarding alumina ceramics, we believe that we still need to actively put forward suggestions so that our researchers and manufacturers can continue to study alumina ceramics to a higher level based on your suggestions.
Popular to this day can be divided into two types, one is the ordinary type and the high-purity type. Here is a brief introduction to the difference between one of these two types. Experiments with different content of al203, such as 190 porcelain, 85 porcelain, 95 porcelain, and 99 and above 99. Among the 90 oxide porcelain materials, it is generally used for wear-resistant ceramics and corrosion resistance. In 85 oxide porcelain, because some talc is often added, it will improve the mechanical strength and electrical performance. It can be sealed with tantalum, molybdenum, niobium, etc., so some are used in electric vacuum The device and equipment will say that the above oxide porcelain has the highest wear resistance, corrosion resistance, and high temperature.
