Electrochemical aluminum and alumina, although the name is similar, in fact, there are significant differences in material characteristics and application fields.

The specific form of electrolytic aluminum, also known as alumina (Al₂O₃), plays an important role in industrial production. It is not a traditional "electrochemical" product of aluminum, but one of the key products in the process of aluminum electrolysis. Electrochemical aluminum is known for its high chemical stability, high hardness, high wear resistance and high melting point, melting point up to 2040℃, is the main raw material for the manufacture of metal aluminum and aluminum alloy. In addition, electrolytic aluminum is also widely used in ceramic products, abrasive materials, fireproof materials and refractory materials, and its unique physical and chemical properties make it one of the indispensable materials in the industry.

In contrast, alumina (Al₂O₃) is a broader concept, which covers the alumina powder or product extracted from the ore and processed. Alumina is not only used as a raw material for smelting aluminum, but also as an analytical reagent, a dehydrating agent for organic solvents, an adsorbent, an organic reaction catalyst and other uses. Its white amorphous powder form allows it to play an important role in many fields.

In summary, although there are certain similarities between electrochemical aluminum and alumina in material characteristics, such as high chemical stability and high hardness, there are significant differences in specific application fields and forms. Electrochemical aluminum is more focused on its specific applications in industrial production, such as metal aluminum and aluminum alloy manufacturing; Alumina is used in a wider range of fields because of its diverse physical and chemical properties.
