We provide multiple specifications of aluminum oxide powder and provide on-demand customization according to customer needs. Contact us today for tailored support! Aluminum oxide is a stable oxide of aluminum, with the chemical formula Al2O3. Also known as bauxite in mining, ceramics, and materials science. Aluminum oxide is a white solid that is insoluble in water, odorless, and extremely hard in nature. It is easy to absorb moisture but not deliquescent (burnt does not absorb moisture). Aluminum oxide is widely used as an analytical reagent, organic solvent dehydration, adsorbent, organic reaction catalyst, grinding agent, polishing agent, raw material for aluminum smelting, refractory material, etc. Aluminum oxide can be widely used in the production of ceramics. Aluminum oxide ceramics have many excellent properties, such as high mechanical strength, high insulation, high hardness, wear resistance, corrosion resistance, and high temperature resistance; Aluminum oxide can also be used as electronic ceramics, such as vacuum devices, circuit substrates, spark plug insulation ceramics, etc. In addition, alumina is also widely used in structural ceramics, chemical ceramic materials, and fine ceramics. When alumina is used for refractory materials, it is mainly used for producing refractory boards, refractory bricks, insulation and other refractory materials. Refractory materials are stacked inside the shell of the smelting furnace, playing a role in insulation and heat preservation. At the same time, it also protects the outer shell of the smelting furnace from being melted by the high temperature inside the furnace. Refractory bricks are mainly used in the metallurgical industry, such as in the construction of steel kilns.
