I don't know if you know about the alumina crucible store. There is no doubt that some of them are unclear. Therefore, it is not very clear what characteristics and main uses the alumina crucible has. Let's help you introduce the characteristics of relevant alumina crucibles and the differences between corundum crucibles.

Alumina crucible characteristics:

99 porcelain with high quality α- Aluminum oxide is the raw material, and its aluminum oxide composition is generally above 99%. 99 aluminum oxide porcelain raw materials are used to make high-temperature crucibles, fire furnace bodies and special metal composite materials, such as ceramic ball bearings, porcelain hydraulic seals and inlet valve plates, as well as wear-resistant components.

1. High purity aluminum oxide, with a composition of more than 99%.

2. Solvent corrosion resistance.

3. Heat resistant, all normal operation is 1600 ℃, 1800 ℃ in a short time.

4. It is resistant to quench and sudden heat and is not easy to burst.

It is formed by grouting with high relative density.

α The composition of aluminum oxide is different. There are many kinds of aluminum oxide in steel jade, such as 75%, 85%, 90%, 95%, 99%, etc., but the reference to alumina crucible should refer to 99%. The higher the iron oxide composition in the raw material of the crucible, the higher the calcination temperature, the better the heat-resistant characteristics. At the same time, the higher the price, the more brittle, and the worse the heat-resistant shock working ability.

Luan001 corundum crucible is composed of molten aluminum trioxide with porous structure. Generally, the specifications and models are different based on the composition of aluminum trioxide, and the color is also different from the appearance. For aluminum trioxide silicide, the selected calcination modifier can affect its tone and application temperature. The corundum crucible is pure aluminum oxide. The application temperature is higher. It is 1600 degrees. All applications are normal. The large application temperature is 1800 degrees. However, the material is brittle and is very easy to crack after melting. If the application temperature standard is not very high (below 1550 degrees), select corundum crucible. If the assets are sufficient, buy a Perkin crucible and reuse it for many times without any environmental pollution.

All the above professional knowledge is about corundum crucible. I don't know how much you have learned. In fact, this professional knowledge is very helpful to you. One of the indirect factors is the mastery of alumina crucibles. There is no doubt that you have understood a lot. Therefore, let's take a good look at the following professional knowledge.
