Hey there! As a supplier of 68% Alumina Bricks, I'm super stoked to spill the beans on the physical properties of these bad boys. Let's dive right in!
First off, let's talk about density. The density of 68% Alumina Bricks is pretty crucial as it gives us an idea about how compact and heavy the bricks are. These bricks typically have a density that ranges from around 2.6 to 2.8 g/cm³. This relatively high density means they're quite solid and can withstand a good amount of pressure. It also implies that they have fewer pores, which is a huge plus when it comes to things like resistance to chemical attacks. If you're using them in an industrial setting where they'll be exposed to harsh chemicals, this low - porosity due to the density helps them stay in good shape for a longer time.
Next up is the thermal conductivity. 68% Alumina Bricks have a thermal conductivity that's in the sweet spot for many applications. It's usually in the range of 2 - 3 W/(m·K). This means they're decent at conducting heat, but not so good that they'll let all the heat escape quickly. In industrial furnaces, for example, you want a material that can hold onto the heat and transfer it in a controlled manner. These bricks do just that. They help in maintaining a stable temperature inside the furnace, which is essential for processes like melting metals or firing ceramics.
Strength is another key physical property. These bricks have a high compressive strength. On average, they can withstand a compressive force of around 40 - 60 MPa. That's pretty impressive! It means they can handle a lot of weight on top of them without cracking or breaking. This makes them ideal for use in the construction of heavy - duty structures like furnace linings. Whether it's the weight of the hot materials inside the furnace or the pressure from the gases, the 68% Alumina Bricks can take it.
The refractoriness of 68% Alumina Bricks is also top - notch. They have a refractoriness of about 1750 - 1790 °C. This means they can resist melting or softening at extremely high temperatures. In high - temperature industrial processes where the temperature can reach up to 1700 °C or more, these bricks remain stable. They don't warp or lose their shape, which is vital for maintaining the integrity of the furnace or other high - heat equipment.
Now, let's touch on the thermal expansion. 68% Alumina Bricks have a relatively low coefficient of thermal expansion. This is important because when a material is heated and cooled repeatedly, it expands and contracts. If the coefficient of thermal expansion is too high, the material can crack due to the stress caused by these dimensional changes. With these bricks, the low thermal expansion means they can go through multiple heating and cooling cycles without significant damage. This makes them highly durable in applications where temperature fluctuations are common.
In comparison to other types of alumina bricks, like the 92% Alumina Lining Brick, 68% Alumina Bricks offer a great balance between performance and cost. The 92% Alumina Lining Brick has higher purity and better performance in some aspects, but it also comes with a higher price tag. The 68% Alumina Bricks, on the other hand, provide sufficient performance for many industrial applications at a more affordable cost.

The color of 68% Alumina Bricks is usually a light beige or off - white. This isn't just for aesthetics; it can also give you an idea about the quality and composition of the bricks. A consistent color indicates a uniform composition, which is a sign of good - quality manufacturing.
These bricks also have good abrasion resistance. In environments where there's a lot of movement of materials, like in some ore - processing plants or coal - fired boilers, the bricks can withstand the wear and tear caused by the abrasion of the moving materials. This helps in extending the lifespan of the lining and reducing the need for frequent replacements.
When it comes to installation, the physical properties of 68% Alumina Bricks make them relatively easy to work with. Their regular shape and size, along with their strength, allow for straightforward installation. They can be easily cut and shaped if needed, which is useful for custom - fitting them into different furnace designs.
In summary, the physical properties of 68% Alumina Bricks make them a versatile and reliable choice for a wide range of industrial applications. Their density, thermal conductivity, strength, refractoriness, low thermal expansion, abrasion resistance, and ease of installation all contribute to their popularity in the market.
