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.
You will get efficient and thoughtful service from AnYiCheng.
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 &#; 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.
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.
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.
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. Pintejin Ceramics is a manufacturer specializing in the production and machining of ceramics, focusing on the machining of alumina ceramic pieces and zirconia ceramics, and can process ceramics according to your needs. product.
The main characteristics of alumina ceramics are:
1. Due to its high temperature resistance, corrosion resistance, and high strength, it is well used in the lining of refractory materials, ceramics, and ironmaking blast furnaces; Spark plugs, high-temperature and anti-oxidation coatings.
2. Due to its high hardness, good wear resistance, and high compressive strength, it is also widely used in chemical systems.
3. Aluminum oxide belongs to the ionic type and has a stable structure. Therefore, it is also widely used in the electronics industry.
4. Aluminum oxide ceramic products have good air tightness and are tightly impermeable even under high temperature resistance, so they are widely used in electric vacuum.
5. The wear resistance of alumina ceramics is good, equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron.
6. Aluminum oxide ceramic insulation materials are also widely used in the walls and roofs of various high-temperature resistant furnaces, which are both heat-resistant and insulated.
7. Aluminum oxide ceramics are lightweight, and the density of ceramic materials is generally not high. Aluminum oxide ceramics are also the same, with a density of only 3.5g/cubic centimeter, which is only 50% of iron. Therefore, if some iron based accessories are replaced with aluminum oxide, their weight will be greatly reduced (of course, due to the high brittleness of aluminum oxide, not all places are suitable).
Disadvantages of alumina ceramics: Although alumina ceramics have many advantages, their limitations are also quite obvious. Due to its high hardness and brittleness, the difficulty of mechanical processing is relatively high, which is also a major reason for the high cost of precision machined parts of alumina ceramics.
