Shaped Refractory

Ordinary sintered alumina needs to add a small amount of sintering aids such as MnO, CuO, TiO2, etc. during the sintering process to reduce the sintering temperature and sintering performance of alumina ceramics, and then promote sintering densification by liquid phase sintering mechanism. Therefore, the porosity of the sintered body is low, the crystals are fine and dense, but its thermal shock resistance is poor.

Sintered tabular alumina is sintered without any additives at a high temperature over 1800°C. Its microscopic observation is a fully developed hexagonal plate-shaped α-alumina crystal, and the grain size is generally greater than 200 μm. Sintered tabular alumina has excellent volume stability and thermal shock resistance In addition, it has extremely high refractoriness, excellent mechanical strength and wear resistance, superior creep resistance and spalling resistance, very high chemical purity , excellent dielectric properties and anti-acid and alkali corrosion ability, can be widely used in steel, casting and ceramic industries, as well as chemical industry heat exchange, energy storage, environmental protection facilities, etc.
