Alumina ceramic tube sintering is a key stage of ceramic preparation, and the sintering atmosphere has a great influence on the preparation of ceramic materials. Too high sintering temperature or too long holding time will promote crystal growth, so that the fine raw materials will develop into coarse grains at high temperature, and the amount of liquid phase will increase. This will not only decrease the strength, but also weaken the wear resistance. Of course, if the temperature is too low, the sintered body will not be dense, and the wear resistance of the product will not be good.

Production practice and a large number of studies show that: low porosity, high density alumina ceramics have excellent structural properties. High density means that the crystal grains in the ceramic body are tightly arranged, and it is not easy to form destructive breakthrough points when subjected to external loads or corrosive substances.

In order to obtain alumina ceramic materials with high wear resistance, not only should it be considered to have high density, flexural and compressive strength, but also to increase its hardness and fracture toughness, and these properties are in line with the obvious characteristics of alumina ceramics. The microstructure (closed porosity, grain size, distribution of glass phase, etc.) and its wear mechanism are closely related.

We are specialized in producing high purity alumina ceramics.

Alumina ceramic belongs to the addition of special ceramics, our factory mainly produces aluminum oxide content is between 99.3% -99.7% of high purity alumina alumina ceramic plate its main composition is AL2O3 as raw material, finished product after sintering hardness can reach mohs hardness grade 9, because it's super abrasion resistance, impact resistance and strong corrosion resistance, high hardness, mechanical performance is remarkable,Has been widely used in cement, steel, thermal power, coal, smelting, chemical, port, mining and other industries in the easy to wear equipment, become to extend the life of mechanical equipment, protect equipment is not easy to be damaged, reduce the enterprise operating costs of the umbrella.

Generally for not very dirty ceramic tube, cleaning is very easy, because only need to use some clean water to wash it can.Because it is very wear-resistant, so you can also use some relatively large friction cleaning tools to clean it, no matter how much you use will not cause any loss to it, so we do not have to worry about this.It's easy to clean up with a brush and some detergent.When cleaning, you can use a water gun with higher pressure to wash it, so that it will be more convenient to wash, but also more clean. I believe that many people will have used such a method.

With the continuous development of science and technology, the use of alumina ceramic tube is more and more widely, alumina ceramic tube will be dirty for a long time, so how to do the alumina ceramic tube dirty?

Alumina ceramics are widely used in the field of lithium battery membrane coating and catalyst carrier because of their excellent physical and chemical properties.

Medical.Alumina is more used to make artificial bones, artificial joints, artificial teeth and so on.Alumina ceramics have excellent biocompatibility, biological inertia, physical and chemical stability, high hardness and wear resistance, and are ideal materials for the preparation of artificial bones and joints.​

Alumina ceramic application field (1) Mechanical aspects.Because of its high hardness, high temperature mechanical properties, good wear resistance, good chemical stability, not easy to bond with metal and other characteristics, it is widely used in hard material cutting, high speed steel cutting, ultra-high speed cutting and other difficult to process materials cutting.
