5 Essential Elements For crucible alumina
High alumina bricks symbolize a specialized category of refractory supplies engineered to withstand Intense temperatures exceeding one,790°C even though protecting structural integrity and chemical security. These bricks possess high refractoriness, fantastic thermal shock resistance, and remarkable mechanical power, creating them perfect for withstanding Severe temperatures and severe working conditions. The elemental characteristic that distinguishes high alumina bricks from standard fire bricks lies inside their elevated alumina (Al2O3) information, usually starting from 45% to 90%, which directly correlates with their Improved overall performance abilities.The commonest strategy to classify high alumina bricks is by their alumina content material. In this article’s a simplified grade reference:
two. For the refractory brick with the Al2O3 articles down below 70%, the refractoriness below load will depend on the quantitative proportion of crystal phase and liquid stage, it raise with the rise in the number of mullite.
Highland Refractory concentrates on making high alumina bricks that Mix Highly developed production with stringent quality Regulate, making certain reliable general performance in demanding industrial ailments.
High alumina refractories are characterized by alumina (Al2O3) written content in between about fifty% to as high as ninety nine%. High alumina bricks are greatly utilized through field in several kinds of programs.
