In terms of chemical properties, aluminum oxide is an amphoteric oxide, reacting with both acids and bases. It exhibits strong chemical stability at high temperatures and is not easily oxidized or reduced.
Aluminum oxide has a wide range of applications in industry. Some specific uses are listed below:
First, in the electrolytic aluminum industry, aluminum oxide is the main raw material for producing aluminum metal. High-purity aluminum metal can be obtained by electrolyzing molten aluminum oxide.
Second, in the ceramics industry, aluminum oxide is used to manufacture various ceramic products, such as aluminum oxide ceramic cutting tools and ceramic crucibles. Due to its high hardness and high-temperature resistance, these ceramic products perform exceptionally well in machining and high-temperature environments.
Furthermore, in the field of refractory materials, refractory bricks and fibers made of aluminum oxide have excellent high-temperature resistance, playing a crucial role in high-temperature furnaces and kilns, protecting equipment and improving production efficiency.
In addition, aluminum oxide is also used in catalysts and catalyst carriers. Its large specific surface area and good chemical stability allow it to effectively support and promote chemical reactions.
