The new material industry is an industry that our country is constantly striving to develop rapidly, and it is developing faster and faster in the ceramic industry. The production of ceramics has driven the scale of many enterprises to become larger and larger.
As one of them, alumina ceramics are becoming more and more mature, but what factors will affect the accuracy of alumina ceramics?
The Accuracy Of Alumina Ceramics
Be-Cu Ceramics is a business model that seeks development with professional technology, fine craftsmanship, quality and integrity.Be-Cu Ceramics is a manufacturer specializing in machining various ceramic components.
At present, Be-Cu Ceramics mainly focuses on precision ceramic machining, mainly including: zirconia ceramic machining, silicon nitride ceramic machining, aluminum nitride ceramic machining, alumina ceramic machining and other advantageous fields . The following editors from Be-Cu Ceramics will introduce to you the factors that change the density of alumina ceramics.
The first thing to say is that alumina ceramics can actually be divided into two categories: very pure alumina ceramics and ordinary alumina ceramics. Among them, the sintering temperature of very pure alumina ceramics is as high as 1800 ℃, and it can be used as an insulating material instead of platinum. Another common type of alumina ceramics is distinguished according to the different content of alumina. The common type of alumina ceramics is mainly used for daily necessities in daily life, such as valve plates, bearings and high temperature resistant crucibles for making ceramics.
Secondly, what factors will change the density of alumina ceramics mainly depends on the properties of alumina itself. In chemistry, alumina is used as a compound, but in technology, alumina can only be used as a kind of material, because alumina is mixed with a lot of impurities, but it is not pure alumina. Among them, the hardness ratio of alumina is relatively high, and it is also an amphoteric oxide, which is easy to ionize and react, and is a very suitable choice for refractory materials. Since high temperature sintering is required in the process of making ceramics, in order to avoid burning out in the middle of high temperature sintering, alumina compounds are selected.
Alumina Is Formed
After the alumina is formed, the high-purification step can be started. If the density requirement cannot always be met, it is necessary to consider whether there is a problem with the raw powder and the formula. There is no problem with adding the raw powder and the formula, then A method of increasing the pressure and increasing the sintering temperature is implemented. However, it should be noted that the high-purification process cannot prolong the holding time, resulting in a very large incidence of grain deformation inside the alumina ceramic. Under normal circumstances, the grains are required to be uniform, so that its organizational composition can be better.
The above are the factors that change the density of alumina ceramics summarized by Be-Cu Ceramics. Alumina ceramics are divided into very pure alumina ceramics and ordinary alumina ceramics; the density of alumina ceramics will be changed by factors, mainly depending on alumina By its nature, alumina is used as a compound in chemistry and as a material in technology. Be-Cu Ceramics is a high-tech enterprise specializing in the production of ceramic injection and precision machining, with strong development and production capacity, application of advanced production equipment and reasonable and innovative production technology.
