What is Alumina?
Alumina is aluminum oxide in its longer form. Alumina is the state of aluminum after going through various processes. Alumina is essential for the production of quality metal. When you want to obtain alumina, the following steps are required. First you have to grind the bauxite ore. After completing the grinding process, you should mix it with lime and caustic soda, and pump the resulting mixture into high pressure vessels. In this way, you can obtain alumina from bauxite ore.The general properties of alumina are that it is hard and has a high melting point. The general information about alumina is as follows: they are not radioactive, retain moisture, do not contain carcinogenic substances, are hard and durable.
What is activated alumina, where is it used?
Activated alumina is used in many industrial plants. It is used to dry liquids and gases. What is activated alumina? We can give the shortest answer to the question by saying it is an adsorbent.
We can also mention electrical transformers and compressors where active alumina is used. We can list the usage areas more broadly.
Usage areas of activated alumina;
1-) In the dehydration process for gases and liquids
2-) When it is desired to purify the refrigerant
3-) In natural gas drying
4-) In air drying systems
It can be counted in different places among the application areas.
What are the Advantages of Activated Alumina?
There are several advantages that lead to the use of activated alumina. At the beginning of these advantages, we can count that it is effective in high humidity. Other advantages are: high moisture retention, resistance to disintegration, high chemical purity.
Thanks to these advantages of active alumina, it helps to absorb moisture from gases and liquids. Thanks to its high moisture retention feature, it is perfect for doing this job.
What Do Alumina Colors Mean?
Alumina can appear in the market with different names. You'll see these names in brown, white, and pink. So what do these colors of alumina mean? Colors express the level of purity and it is possible to say that the usage areas change according to their colors. We can consider them separately according to their colors.
Alumina colors and properties by color
1-) Brown alumina: Brown alumina is quite durable. Besides its durability, it can resist high pressure. Its resistance to abrasion is also quite high. Among the usage areas, there is the cleaning of the automotive sector and the aviation sector. Matting of various materials, sandpaper manufacturing, glass decoration processes are some of the usage areas.
2-) White alumina: The purity of white alumina is 99 percent. It is harder when compared to brown alumina. It has a very high melting point and a large crystal size. It is also used for smoothing surfaces.
3-) Pink alumina: Wet and dry sandblasting can be done by using pink alumina. As with other alumina, they have a hard and durable structure.The common feature of different aluminas is that they have hard structures. However, we can say that the cost is advantageous. These are the main reasons for its use. It can also be used due to the long life of alumina according to its structure.
