Aluminum Oxide (CAS 1302-74-5), often referred to as Alumina, is a fundamental inorganic material with a remarkably diverse range of industrial applications. Its unique combination of properties makes it indispensable in sectors spanning from manufacturing and construction to electronics and chemicals. For R&D scientists and product developers, understanding these properties and identifying reliable sources for purchase is key to innovation.

The chemical composition of Aluminum Oxide is Al2O3. It is known for its exceptional hardness, second only to diamond, making it a prime candidate for abrasive applications. Grinding, cutting, and polishing tools extensively use Aluminum Oxide powders. Its high melting point (around 2072°C) and resistance to thermal shock also make it a critical component in refractory materials, essential for lining high-temperature industrial equipment such as furnaces and kilns. Manufacturers looking for robust materials for extreme environments often turn to this compound.

Chemically, Aluminum Oxide is amphoteric, meaning it can react with both acids and bases. While it is virtually insoluble in water, it exhibits excellent resistance to chemical attack from many corrosive substances. This chemical stability, coupled with its electrical insulating properties, leads to its extensive use in the electronics industry for substrates, insulators, and protective coatings. Its dielectric strength is particularly noteworthy.

The production of Aluminum Oxide typically involves the Bayer process, which refines bauxite ore. The resulting product can be further processed and classified into various grades depending on its intended use, including activated, acidic, basic, and neutral grades. Each grade possesses specific surface characteristics and reactivity, making them suitable for distinct applications, such as chromatography, catalyst supports, or water treatment. Purchasing Aluminum Oxide often involves specifying the desired grade and purity.

For businesses looking to buy Aluminum Oxide, understanding the market dynamics and identifying reliable manufacturers is crucial. China has a significant presence in the global supply of Aluminum Oxide, offering a wide spectrum of grades and quantities at competitive prices. When inquiring about price, it is essential to clearly state the CAS number (1302-74-5) and the required purity to receive an accurate quote. Suppliers often provide detailed technical data sheets and samples for evaluation.

In conclusion, Aluminum Oxide is a material of immense industrial importance due to its hardness, thermal stability, and chemical resistance. Whether you need it for abrasives, refractories, ceramics, or chemical processes, identifying a reputable manufacturer and supplier is paramount for securing high-quality material at a competitive price. Engaging with experienced suppliers who can provide comprehensive product information will ensure you make an informed purchasing decision.
