Industry Knowledge of High Alumina Refractory Mortars

High alumina refractory mortars are commonly used in various industrial applications due to their ability to withstand high temperatures and harsh chemical environments. These mortars are typically composed of high levels of alumina, which is a highly stable and heat-resistant material that can withstand temperatures up to 1800°C.

There are different types of high alumina refractory mortars available in the market, with varying levels of alumina content. LN-50 has an alumina content of at least 50%, LN-60 contains at least 60% alumina, NN-42 contains at least 42% alumina, and LN-70 contains at least 70% alumina.

The differences in alumina content between these types of high alumina refractory mortars determine their specific properties and applications. Mortars with higher alumina content have higher resistance to corrosion and erosion and are therefore suitable for use in harsher and more aggressive environments.

LN-50 and NN-42 are typically used in low-temperature applications, such as the construction of fireplaces and ovens. LN-60 is suitable for use in higher temperature applications, such as kiln linings and furnace walls. LN-70, with its highest alumina content, is the most heat-resistant and is typically used in applications where temperatures exceed 1600°C.

In addition to their high alumina content, high alumina refractory mortars also exhibit good workability and bonding properties, making them easy to use and providing excellent adhesion to refractory materials. All these qualities make high alumina refractory mortars an essential material for different industries that require strong and heat-resistant materials.

In conclusion, high alumina refractory mortars are a reliable and efficient material for a range of industrial applications. The different types of high alumina refractory mortars available cater to various temperature and environmental needs in various industries. Their contribution to the progress of various industrial sectors cannot be overemphasized.
