High alumina brick refractories might have two bond devices, ceramic, and phosphate. Phosphate brick is instantly regarded by a phosphorus pentoxide (P2O5) information on their details sheet of amongst about 3% and six%.
one. On the list of significant Doing work Qualities of high alumina refractory brick is the framework power at high temperature. This attribute is often evaluated through the deformation temperature of refractoriness.

Porosity: Very low-porosity bricks are denser plus more resistant to chemical attacks, making them ideal for harsh circumstances.
7. The high aluminum brick has higher thermal conductivity than the clay brick, that's related to the lower of glass section within the high alumina brick and the increase of mullite crystal or corundum crystal.
three. For that mullite- corundum refractory brick with the AL2O3 information of 70% ~ 90%, the material of AL2O3 raises, but the improvement of refractoriness less than load is not really evident. This is certainly due to partial softening on ceramic crucible with lid the mullite crystals at high temperature as well as a slight increase in the level of flux impurities that interact with the mullite crystals.
A phosphate chemical addition reacts with no cost alumina during the brick blend to variety an aluminum ortho-phosphate chemical bond during medium temperature curing. Firing a phosphate-bonded brick to higher temperatures results in a composition which includes both of those phosphate and a ceramic bond.

Resco generates quite a few LADLEMAX brick products that have varying compositions associated with magnesia, carbon, and addictive contents.
As a frontrunner in the sphere of refractory products, we understand the critical function that high alumina bricks Perform in different industrial processes, from steelmaking to cement production.
These bricks perform extremely nicely in environments where standard fireclay bricks would fall short—Particularly less than direct flame, chemical attacks, or high mechanical load.
