Phosphate-bonded high alumina brick is favored in lots of aluminum furnace linings as the phosphate triggers the brick being resistant to wetting and penetration by molten aluminum. Phosphate-bonding also enhances the refractory Houses by increasing density, reducing porosity, raising toughness, and abrasion resistance.
Ship us your furnace form, running temperature, and amount—we’ll assistance you end up picking the very best high alumina brick Remedy for your requirements.
In creation, the thermal shock resistance of refractory bricks is often enhanced by increasing the particle framework qualities of firebricks or adding a specific number of synthetic cordierite (2Mg0.2AI203.5Si0z) along with other minerals within the batching
The quantity and Homes of your liquid phase have a substantial affect about the refractoriness less than load. Therefore, the reduction in the impurity articles in Uncooked substance is in favor of improving upon the refractoriness under load and high temperature creep properties.
One example is, resistance to penetration and wetting by molten aluminum could be enhanced with a phosphate bond. Consult your Resco sales consultant or business expert to determine acceptable high alumina brick for your application.
These bricks are manufactured by firing raw components like bauxite and kaolin at high temperatures, leading to a dense, resilient product or service which can withstand extreme heat and severe conditions.
Measurement and Shape: Ensure the bricks can be found in the sizes and styles necessary for your furnace or kiln lining.
A phosphate chemical addition reacts with absolutely free alumina during the brick mix 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 in addition to a ceramic bond.

Only when the changeover into the refractory brick which consists Practically totally of corundum firebrick, that is certainly to mention, when the Al2O3 content is much more than ninety five%, high power at high temperature is clearly enhanced.
Alumina-dependent refractorys are an indispensable materials for industries that work beneath extreme temperatures and harsh conditions. With their unmatched heat resistance, toughness, and chemical stability, they supply a responsible Resolution for your refractory demands.
