Load Softening Temperature of Zirconium Corundum Brick

2023-08-01 10:20:05

Zirconia corundum brick is a high-temperature material mainly composed of zirconia (ZrO2) and alumina (Al2O3). The name of the zirconia corundum brick comes from the corundum (Al2O3) in its main components, zirconia (ZrO2) and alumina (Al2O3).

Zirconium corundum brick is a white solid formed by melting alumina powder and zircon sand containing 65% zirconia and 34% silicon dioxide in an electric furnace and then pouring it into the model to cool. The composition of the eutectoid and the glass phase of the stone is a eutectoid of the corundum phase and the zirconite phase, and the glass phase is filled between their crystals.

Zirconium corundum bricks have high compressive strength, high-temperature stability, and corrosion resistance, so they are widely used in high-temperature industries and scientific fields. It can withstand use under severe conditions such as high-temperature thermal shock, thermal stress, and chemical erosion. Common applications include high-temperature furnaces, melting furnaces, electrolytic cells, etc.

The load-softening temperature of zirconium corundum bricks is around 1700°C. Zirconium corundum brick is a high-temperature material, mainly composed of zirconia and alumina, which has good high-temperature stability and corrosion resistance, so it is widely used in industrial and scientific fields under high-temperature environments. The load softening temperature refers to the temperature at which the material begins to soften and deform under a certain load.
