Temperature Control in the Sintering Process of Alumina Ceramics

The temperature difference and time required for high-temperature firing treatment of alumina ceramic blanks after forming have a significant impact on the finished product. Therefore, there are strict requirements for the performance and quality of alumina ceramic ceramics in terms of firing temperature, which requires precise control of the sintering temperature of alumina ceramics. Therefore, we should take corresponding measures.

Different alumina ceramics also have different sintering temperature requirements, and the sintering temperature is actually related to the content of alumina. In theory, if the alumina content is higher, the sintering temperature will be higher. In fact, this statement is not entirely absolute, and it is necessary to observe the composition and proportion of ceramic materials. Generally, when manufacturing and producing alumina ceramics, we need to consider various factors, try to reduce the sintering temperature as much as possible, and ensure the effect of reducing consumables.

We can start with aluminum oxide additives and add solid solution solvents appropriately to aluminum oxide ceramics. However, many friends do not understand the purpose of this approach. This can achieve a more obvious cooling effect, but there are also many disadvantages. If it is not sintered in liquid phase, it will be very difficult to fill the pores of the crystal.
