A, refractoriness
High alumina brick refractoriness than clay brick and semi-silica brick refractorance should be high, up to 1750 ~ 1790 ℃, are high refractories.
B, load softening temperature
Because high-alumina products in the high Al2O3, less impurities, the formation of fusible glass less, so the load softening temperature than the clay brick, but the mullite crystallization does not form a network of organizations, so the load softening temperature is still no silicone bricks.
C, slag resistance
High alumina brick Al2O3, close to the neutral refractory material, can resist the acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkali-resistant slag than the ability of acid-resistant slag weak.
