Phosphate-bonded high alumina brick is preferred in lots of aluminum furnace linings as the phosphate leads to the brick being resistant to wetting and penetration by molten aluminum. Phosphate-bonding also improves the refractory Houses by increasing density, lowering porosity, raising toughness, and abrasion resistance.
High alumina brick refractories may have two bond methods, ceramic, and phosphate. Phosphate brick is quickly acknowledged by a phosphorus pentoxide (P2O5) content on their own information sheet of between about 3% and six%.
In manufacturing, the thermal shock resistance of refractory bricks is often enhanced by increasing the particle construction qualities of firebricks or adding a specific number of synthetic cordierite (2Mg0.2AI203.5Si0z) as well as other minerals in the batching
The amount and Attributes from the liquid stage have a big impact on the refractoriness below load. For that reason, the reduction with the impurity content in raw materials is in favor of strengthening the refractoriness underneath load and high temperature creep Houses.

Dimension and Condition: Ensure the bricks can be found in the sizes and styles necessary for your furnace or kiln lining.
In particular, the composition of Ti02. Fe203 increases marginally with the increase of Al203 articles from the Uncooked substance, which improvements the amount and Houses with the high temperature liquid period.
