1. In terms of machinery, the bending strength of Al2O3 porcelain sintered products can reach 250Mpa, and the hot-pressed products can reach 500Mpa. The Mohs hardness of Alumina ceramic can reach 9, and it has excellent wear resistance, so it is widely used in the manufacture of tools, ball valves, grinding wheels, ceramic nails, bearings, etc. Among them, Al2O3 ceramic tools and industrial valves are widely used.

Because alumina ceramics have relatively unique properties and have been valued in the market, the main thing is that they have also attracted the development and research of researchers, so that it can be used in air pollution control, the possibility of molten metal filtration, etc. However, many existing problems still need to be resolved in a timely and effective manner.

Alumina ceramic parts are used in many industrial production occasions, which fully shows that ceramic parts have many superior properties compared to other materials, and they will become popular in the industry. At present, alumina ceramics can be mainly used for protection tubes and insulating tubes of temperature measuring instruments, thermocouple thermometers; at the same time, it can also be used in furnace tubes of industrial resistance furnaces, experimental electric furnaces, and heat treatment furnaces.

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.

Grouting is actually an early molding method used for alumina ceramics. Because plaster molds are mainly used, the cost is relatively low, and it is also relatively easy to shape, even if the size and shape are more complex, it is easier to shape, but The key to grouting is the alumina slurry manufacturing equipment. Under normal circumstances, water is used as the main medium of the solvent. After that, the binder and debonding agent are added, and the exhaust is exhausted after sufficient grinding. It is poured into the plaster mold, because the capillary of the plaster mold will absorb the moisture, and the slurry will solidify in the plaster mold relatively quickly. If required, the excess material needs to be poured out, but in order to reduce the amount of shrinkage of the green body, we should try to use a relatively high-concentration slurry.
