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.

Refractory materials

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.



The electronics industry

Aluminum oxide has a wide range of applications in the electronics industry, mainly as a basic material for electronic components. Due to its excellent insulation performance, high thermal conductivity, and conductivity, it can be used to manufacture capacitors, resistors, transistors, integrated circuits, and semiconductor devices. Aluminum oxide can also be used as a heat sink and packaging material for electronic devices, ensuring their normal operation.
