Advantages and disadvantages of alumina ceramic sheets and how to identify them

With the continuous development and progress of science and technology, alumina ceramic sheets with superior performance have been widely used in various fields. So what are the advantages and disadvantages of alumina ceramic sheets and how to identify them? Next, Pintejin ceramics will introduce to you.

First of all, we will introduce alumina ceramic sheets. Alumina ceramic sheets are also called wear-resistant alumina ceramic linings, high-alumina linings, wear-resistant ceramic linings, alumina ceramic patches. Alumina ceramic sheets are mainly made of AL2O3 as raw materials. It is calcined at a high temperature of 1700 ℃ with rare metal oxides as a solvent.

Because of its relatively dense structure and special properties, it is called special ceramics. Alumina ceramic material is a densely packed hexagonal structure composed of oxygen ions, and aluminum ions are filled in two-thirds of the octahedral gap, so alumina. The ceramic sheet has high melting point, high hardness and excellent wear resistance.

Moreover, the surface is smooth and the friction coefficient is small, and the wear resistance is very ideal, especially in high temperature oxidizing medium or corrosive medium, the material of alumina ceramic patch is much better than other metal materials.

How to identify alumina ceramic sheets

First of all, we have to look at the surface of the alumina ceramic sheet. The surface of a good alumina ceramic sheet is very smooth, with no black spots on the surface and uniform color.

Secondly, we can identify the alumina ceramic sheet by measuring the density. The content of alumina can be known by measuring the density. Another method is to identify the quality of the alumina ceramic sheet by doing a wear test. The product has its positive reverse side.

Advantages of alumina ceramic sheets

Alumina ceramic sheet has high mechanical strength, good wear resistance, good corrosion resistance, good impact resistance, good thermal stability, abundant raw materials, low price, and environmentally friendly and pure products.

Disadvantages of alumina ceramic sheets

The ability of post-machining is low, and the product is not suitable for recycling.

The above are the advantages, disadvantages and identification methods of alumina ceramic sheets brought to you by Pintejin Ceramics.
