The production of alumina ceramics has the same features as the production of traditional ceramics. A good ceramic product must have good raw materials + good molding process + good sintering system + good grinding processing + other excellent production links. Let's start with the raw materials. The material of alumina ceramics generally refers to α alumina. Select the corresponding material according to the type of ceramic you want to make, such as dielectric ceramics. We mainly look at whether its sodium oxide content is low sodium alumina powder. We must look at the D50 of his powder and the overall particle size distribution of his powder.
