Refractory *9% Alumina Tabular Sintering Alumina White Tabular Alumina Tabular Corundum Plate Alumina
Tabular corundum, also known as sintered tabular alumina, is a
high-purity form of alumina (Al2O3) that is specifically processed
to have a unique tabular, or flat, shape. It is produced by
sintering (heating without melting) high-grade alumina powder at
temperatures above ***0C, causing the alumina particles to grow and
form large, flat, plate-like crystals.
Tabular corundum offers several advantages in various industrial
applications due to its distinctive properties: High Purity,
Excellent Thermal Stability, High Mechanical Strength, Low
Porosity, Dimensional Stability, etc.
Overall, tabular corundum, or sintered tabular alumina, is highly
valued for its purity, thermal stability, mechanical strength, and
low porosity, making it a versatile material in various industrial
applications, particularly in refractories and ceramics.
Usage: Tabular
corundum is widely used in high-performance refractory materials in
the fields ofsteel, casting, petrochemicals,
breathable bricks, ladle linings, castables, prefabricated parts,
ceramics and other fields. It is an
excellent synthetic refractory raw material. Tabular corundum is
used asRefractory
aggregatecan be used
in combination with spinel, calcined activated alumina and binding
agents such as cement, clay or resin. The prepared high-purity
corundum bricks have low impurity content (such as SiO2), high bulk
density and good thermodynamic properties, making corundum bricks
Bricks are resistant to thermal, chemical and structural damage
caused by the operation of gasifiers and other industrial
furnaces.
Advantages:high
refractoriness; high corrosion resistance; high erosion resistance;
high thermal shock resistance; high strength, good toughness;
stable chemical properties; resistance
to alkaline slag erosion, good resistance to slag erosion, and good
resistance to molten iron erosion ; Resistant to erosion by molten
steel and good air permeability.
Tabular corundum, orsintered tabular alumina, finds application in a wide range of industries and processes due to its unique properties. Some of the key applications of tabular corundum include:
Refractories: Tabular corundum is extensively used in the production of refractory materials, which are crucial for high-temperature applications. It is used as a raw material in the manufacturing of refractory bricks, monolithic refractories, and shaped refractory products.
