What is the production process of alumina ceramic parts?

What is the production process of alumina ceramics? I believe many people do not know that alumina ceramics will be used in many industrial production situations. This means that the more ceramic ceramics have many superior properties compared to other materials. Will be popular in the industry. How is such a good ceramic porcelain produced?

Alumina ceramic products are formed by various methods such as dry pressing, grouting, extrusion, cold isostatic pressing, injection, casting, hot pressing and hot isostatic pressing.
The production process of alumina ceramics is generally divided into three main steps. To ensure its quality, every step must be done. First, the preparation of ceramic powder as raw material. If you make general-purpose ceramic porcelain, there are ready-made spray-dried granulated powders on the market; if you need to control the formulation of your own materials, you need to buy ball mills and balls as well as spray dryers. With the raw material, press forming can be started. For sheet products smaller than 2 mm, gel forming can be considered. For ceramics larger than 2 mm, press forming can be considered. .
At present, alumina ceramics can be mainly used for protection tubes and insulating tubes of thermocouple thermometers for temperature measuring instruments; it can also be used in furnace tubes of industrial resistance furnaces, experimental electric furnaces and heat treatment furnaces. In addition, steel chemical analysis of carbon tubes and fixed sulfur tubes, as well as other high temperature, acid and alkali corrosion resistant instrument components must use ceramic porcelain as a basic part.

It seems that alumina ceramics use its strong mechanical strength, thermal shock resistance; good thermal conductivity, insulation; and high softening temperature advantages, which have come in handy in many industries, which is of great significance.
