Phosphate-bonded high alumina brick is desired in several aluminum furnace linings because the phosphate brings about the brick to become proof against wetting and penetration by molten aluminum. Phosphate-bonding also increases the refractory properties by rising density, decreasing porosity, growing energy, and abrasion resistance.
High alumina brick refractories might have two bond devices, ceramic, and phosphate. Phosphate brick is readily regarded by a phosphorus pentoxide (P2O5) information on their data sheet of involving about 3% and six%.
Glass Industry: Great for glass melting furnaces thanks to their power to withstand high temperatures and resist alkali assaults.
In order for you a customized High Alumina Brick Option for the furnace, or will need technical specs and offers, Make contact with our Highland Refractory expert today to get your cost-free session.
High alumina refractories are characterized by alumina (Al2O3) articles concerning roughly 50% to as high as 99%. High alumina bricks are commonly made use of all through market in lots of sorts of purposes.
With a commitment to international cooperation, we goal for being your reputable lover, furnishing top-notch products and services to customers globally.
A Resco sales consultant or business apps specialist may help you pick the right alumina brick for the software.
A phosphate chemical addition reacts with free of charge alumina while in the brick combine to type an aluminum ortho-phosphate chemical bond in the course of medium temperature curing. Firing a phosphate-bonded brick to higher temperatures leads to a composition that has both phosphate and a ceramic bond.

Picking the ideal variety of high alumina brick hinges on aligning alumina content material, specialized requirements, and Proportions with your operational desires. Regardless of whether you call for standard T-three bricks for your blast furnace or tailor made zirconia-Increased models for just a petrochemical plant, understanding these elements guarantees longevity and efficiency in high-temperature environments.
Increased Actual physical strength and abrasion resistance make phosphate-bonded brick compositions desired in abrasive apps, together with pebble lime kiln feed finishes and applications that characteristic abrasive dust entrained in a very high-velocity fuel stream.
The alumina bricks manufacturing method starts with the watchful number of quality bauxite ore, which serves as the primary Uncooked material because of its high alumina material and minimal impurity amounts. Through production, the bauxite undergoes calcination at temperatures exceeding 1,400°C to remove humidity and risky compounds, making a stable ceramic materials. The manufacturing process proceeds with exact grinding and sizing to realize ideal particle distribution, followed by the addition of binding brokers and forming additives that enrich workability in the course of the shaping stage.
