seven. The high aluminum brick has higher thermal conductivity compared to the clay brick, that is related to the lessen of glass stage in the high alumina brick and the rise of mullite crystal or corundum crystal.
Kerui Information 2025-03-seventeen High alumina bricks are indispensable refractory materials commonly used in industries which include steelmaking, cement creation, and glass producing. Comprehension the kinds of high alumina bricks, their technical specs, Proportions, and packaging standards is critical for selecting the ideal item in your software.
A phosphate chemical addition reacts with no cost alumina during the brick blend to sort an aluminum ortho-phosphate chemical bond all through medium temperature curing. Firing a phosphate-bonded brick to higher temperatures brings about a composition which has equally phosphate plus a ceramic bond.
The mineralogical framework develops in the high-temperature firing system, where the Uncooked elements undertake elaborate chemical reactions and period transformations. Corundum crystals sort when alumina information exceeds 72%, offering Excellent hardness and thermal stability. Mullite development happens throughout the reaction between alumina and silica, building needle-like crystals that enrich mechanical energy and thermal shock resistance. Knowing these structural developments enables brands to enhance the alumina bricks manufacturing system for precise functionality needs and software needs.
Only once the transition to the refractory brick which consists Just about fully of corundum firebrick, that is definitely to state, once the Al2O3 content material is greater than ninety five%, high energy at high temperature is obviously enhanced.

As a leader in the sector of refractory materials, we fully grasp the crucial job that high alumina bricks Perform in many industrial processes, from steelmaking to cement creation.
Their versatility tends to make them acceptable not simply for high-temperature zones but in addition for structural help in furnace high alumina bricks partitions and roofs.
