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.

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.

In fact, there are many types of alumina ceramics. If they are classified according to the main content of alumina, alumina ceramics can be divided into many types. Let’s learn about the characteristics and characteristics of the next several different alumina ceramics. Use it!

Alumina ceramics are more and more widely used, and the wear on the industrial stamping elbow is the main factor affecting the entire safety production. In order to effectively reduce the wear failure caused by the entire industry for stamping elbows, many new materials and more wear-resistant materials have emerged. However, only alumina ceramic materials are actually used. Because alumina ceramics is very good in wear resistance, the main thing is that its hardness is relatively high. It is only used in the industrial stamping elbow industry, and it is also widely used in many other aspects.

Jinzhou Yunxing Industrial Ceramics Co., Ltd. National Day holiday time: October 1st to October 7th. We normally accept order consultation during the holidays and arrange production after the holiday.

From the current point of view, the general development trend of armor materials is toughness, light weight, multi-function and high efficiency. Alumina ceramic material is an important part of bulletproof materials. It has high hardness and wear resistance, high compressive strength and excellent ballistic performance under high stress.

The application of alumina ceramics in modern society has surpassed our imagination, and its application has become more and more extensive. It has met our daily needs and special performance needs. Since the application of alumina ceramics is so extensive, let us take a look at the hardness of alumina ceramics.

Alumina ceramics have been widely used, and the market demand is also increasing. Therefore, there are more and more alumina ceramic manufacturers. So how should alumina ceramic manufacturers choose? Let's analyze it for everyone below.
