Hey there! As a supplier of Brown Corundum, I often get asked whether this material can be used in high - temperature applications. Well, let's dive right into it and find out.
First off, let's understand what Brown Corundum is. Brown Corundum is also known as Brown Fused Aluminum Oxide. It's made by fusing high - purity bauxite in an electric arc furnace at extremely high temperatures. The result is a tough, wear - resistant material that has a wide range of uses.
Properties of Brown Corundum
Brown Corundum has some really cool properties that make it a strong candidate for high - temperature scenarios. One of its key features is its high melting point. The melting point of Brown Corundum is around 2050°C. This means that it can withstand incredibly high temperatures without melting or deforming easily.
Another great property is its high hardness. On the Mohs scale, Brown Corundum has a hardness of about 9. This hardness gives it excellent wear resistance. In high - temperature applications, where materials are often subject to friction and abrasion, this hardness is a huge advantage.
It also has good chemical stability. It won't react easily with most chemicals, even at high temperatures. This makes it suitable for use in environments where there might be corrosive substances present.
High - Temperature Applications of Brown Corundum
Refractory Materials
One of the most common high - temperature applications of Brown Corundum is in the production of refractory materials. Refractory materials are used in industries like steelmaking, glassmaking, and cement production, where they need to withstand very high temperatures.
In steelmaking, for example, the lining of the blast furnace is often made with refractory bricks that contain Brown Corundum. These bricks can withstand the extremely high temperatures inside the furnace, which can reach up to 1600°C or even higher. The high melting point and wear resistance of Brown Corundum ensure that the refractory lining lasts a long time, reducing the need for frequent replacements.
Abrasive Tools
Brown Corundum is also widely used in the manufacturing of abrasive tools. In high - temperature abrasive applications, such as grinding and cutting metals at high speeds, the heat generated can be quite significant.
For instance, when using a grinding wheel made with Brown Corundum to grind stainless steel, the friction between the wheel and the metal can cause the temperature to rise rapidly. Thanks to its high melting point and hardness, the Brown Corundum in the grinding wheel can maintain its shape and cutting ability even under these high - temperature conditions.

Thermal Spraying
Thermal spraying is another area where Brown Corundum can be used in high - temperature applications. In thermal spraying, a material is heated to a molten or semi - molten state and then sprayed onto a surface to form a coating.
Brown Corundum can be used as a feedstock in thermal spraying processes. The high - temperature flame in the thermal spraying equipment melts the Brown Corundum particles, which then adhere to the surface being coated. This creates a hard, wear - resistant coating that can protect the underlying material from high - temperature corrosion and abrasion.
Challenges in High - Temperature Use
While Brown Corundum has many advantages for high - temperature applications, there are also some challenges. One of the main challenges is thermal shock. When the temperature changes rapidly, Brown Corundum can crack due to the stress caused by the different rates of expansion and contraction.
To overcome this, special processing techniques can be used to improve the thermal shock resistance of Brown Corundum. For example, adding certain additives during the manufacturing process can help to reduce the internal stress and make the material more resistant to thermal shock.
