The Fireclay Acid Resist Acid Brick is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks.
In addition to the high refractory mullite crystals, the clay bricks also contain nearly half of the low melting point amorphous glass phase.
In the temperature range of 0~1000℃, the volume of Fireclay Acid Resist Acid Brick expands uniformly as the temperature rises.
The linear expansion curve is approximately a straight line, and the linear expansion rate is 0.6%~0.7%, which is only about half of that of silica bricks.
When the temperature reaches 1200 ℃ and then continue to rise, its volume will start to shrink from the maximum expansion.
The residual shrinkage of Fireclay Acid Resist Acid Brick leads to the loosening of mortar joints in masonry, which is a major disadvantage of clay bricks.
When the temperature exceeds 1200°C, the low melting point substances in the Fireclay Acid Resist Acid Brick gradually melt, and the particles are tightly pressed against each other due to surface tension, resulting in volume shrinkage.
Production practice in China has proved that before crushing, high-aluminum clinker is strictly sorted and classified, and stored in tiers.
The use of bauxite clinker and combined clay fin grinding method can improve product quality.
