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.

As a core special structural ceramic for industrial applications, alumina ceramic tubes feature superior electrical insulation, exceptional wear resistance, strong chemical inertness and outstanding thermal stability. They are widely applied across full-spectrum scenarios including laboratory tube furnaces, semiconductor diffusion furnaces, transportation of corrosive chemical media, sintering of new energy lithium batteries, and high-frequency electrical insulation in industrial equipment.

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.

1, alumina ceramic pipe: all kinds of wear-resistant, high-temperature ceramic lined pulverized coal, tailings, slag slurry, slurry pipeline, elbow, elbow tube, pulverized coal burner, coal mill export, coarse and fine powder cyclone separator, chute, hopper, storage bin, mine magnetic separator beneficiation barrel body;

In terms of application scenarios, 99.3% alumina ceramic tubes are highly adaptable and widely used in multiple booming industrial sectors. I. Iron and steel plant: 1. Lining of cylinder mixer of sintering machine 2, drum package ceramic rubber 3. Fan impeller 4, disc feeder, dry trough 5, coke hopper, converter bin, coke tank weighing hopper, cyclone dust collector

According to industry technical experts, the excellent wear resistance of alumina ceramic tubes stems from their dense and stable sintered crystal structure of high-purity alumina.

Generally for not very dirty alumina 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.I

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?

In recent years, with the rapid development of high-end manufacturing, new energy, electronic semiconductors and other fields, the market's performance requirements for alumina industrial ceramics have continued to rise, and production technologies have achieved continuous innovation and breakthroughs.
