High-aluminum refractory castable is a type of refractory castable whose main component is high-aluminum oxide. It is usually made from high-purity aluminate minerals as raw materials, which are sintered, ground and mixed.

High alumina brick is a kind of refractory material. The main component of this refractory brick is Al2O3. If the Al2O3 content is higher than 90%, it is called corundum brick. Due to different resources, national standards are not completely consistent. For example, European countries stipulate that the lower limit of Al2O3 content for high-aluminum refractory materials is 42%. In China, high alumina bricks are usually divided into three grades according to their Al2O3 content: Grade I - Al2O3 content >75%; Grade II - Al2O3 content 60-75%; Grade III - Al2O3 content 48-60%.

Magnesia-alumina spinel brick refers to a synthetic spinel refractory raw material using magnesium oxide and aluminum trioxide as raw materials. This raw material is rarely found in nature, and magnesium-aluminum spinel used in industry is all artificially synthesized. Bauxite-based sintered magnesia-aluminum spinel uses high-quality alumina with an Al2O3 content of more than 76% and high-quality light-burned magnesium powder with an MgO content of more than 95%. After a multi-stage homogenization process, it is heated to 1800°C in an ultra-high temperature tunnel kiln. It is sintered at the above high temperature.

Calcium aluminate is an inorganic salt with the chemical formula 3CaO·Al2O3. It is a white cubic crystal. Relative density 3.038, decomposes when heated to 1535°C. Insoluble in water, soluble in acid. It is commonly found as hexahydrate with a molecular weight of 377.96 and is a spherical colorless or white crystalline powder. Relative density 2.49, refractive index 1.605. It begins to dehydrate when heated to 250°C, begins to decompose and releases crystal water at 300°C, and decomposes at 700~800°C. It also decomposes when placed in water. It is prepared by reacting sodium aluminate with calcium chloride and calcium hydroxide. Used to make concrete accelerator

High alumina fine powder is widely used in the production of refractory materials such as refractory bricks, refractory cement and refractory castables. Its high hardness and wear resistance make it an ideal material to resist high temperature wear. In addition, high-aluminum fine powder also has excellent fire resistance and can withstand extremely high temperatures, so it is widely used in high-temperature industrial environments.

High-aluminum heat-resistant mortar is a heat-resistant material made of kaolin and molten bauxite as the main raw materials, adding an appropriate amount of binders, stabilizers and additives. High-aluminum heat-resistant mortar is mainly used for heating, cooling and thermal insulation joint filling in high-temperature kilns and hearths.
