Aluminum Oxide, identified by CAS number 1302-74-5, is a fundamental inorganic chemical compound with a broad spectrum of industrial applications. Its robust physical and chemical characteristics make it a preferred material in demanding environments across various sectors. For professionals in research and development or procurement, a deep understanding of this material is essential when considering its purchase.

Physically, Aluminum Oxide typically presents as a white powder. It possesses an extremely high melting point of approximately 2072°C (3762°F) and a boiling point around 2977°C (5391°F). This thermal stability is a key attribute for its use in high-temperature applications like refractory linings and kiln furniture. The density of Aluminum Oxide is around 3.95 g/cm³, making it relatively dense for a powder but contributing to its mechanical strength in ceramic forms. Its insolubility in water and resistance to most acids and alkalis further enhance its utility in harsh chemical environments.

The chemical nature of Aluminum Oxide is amphoteric, allowing it to react with both strong acids and strong bases. This characteristic is leveraged in certain chemical processes and also means that material compatibility needs to be considered during handling and application. As an electrical insulator, it has critical applications in the electronics and electrical engineering fields, preventing current flow while withstanding high operating temperatures.

Industrially, Aluminum Oxide is produced through various methods, with the refining of bauxite ore being a primary route. The resulting material can be processed into different grades, such as activated alumina, which has a high surface area and is used for adsorption and as a catalyst support. Neutral, acidic, and basic grades are also common, catering to specific catalytic or chromatographic needs. When you buy Aluminum Oxide, specifying the correct grade is paramount to achieving the desired performance in your formulation or process.

For procurement specialists, sourcing Aluminum Oxide involves identifying reliable manufacturers and suppliers who can consistently deliver the required quality and quantity. China remains a significant source for this chemical, offering competitive pricing and a wide array of product specifications. It is prudent to request detailed product specifications, including purity levels, particle size distribution, and available grades, along with a price quote. Understanding the CAS number 1302-74-5 ensures you are referencing the correct substance.

In summary, Aluminum Oxide is a highly versatile and robust inorganic compound with properties that make it invaluable across numerous industries. Its thermal stability, hardness, and chemical inertness are just a few of its defining characteristics. For those looking to purchase this material, working with knowledgeable suppliers who can provide technical data and competitive pricing is the best approach to ensure successful integration into your applications.
