Product Details



Alumina has a density between 3.5-3.9g/cm3 and is an important inorganic compound with a variety of uses and properties. It is insoluble in water at room temperature, has good electrical conductivity, and is an ionic crystal. Its physical and chemical properties make it widely used in many fields.

 

Here is a detailed introduction to some of the key characteristic parameters of aluminum oxide:

Melting point and boiling point: The melting point of aluminum oxide is 2054℃ and the boiling point is 2980℃. These high-temperature properties make aluminum oxide highly thermally stable and able to maintain its physical and chemical properties unchanged in high-temperature environments.

 

Density: The density of aluminum oxide is between 3.5-3.9g/cm3, which indicates that it has a high density and is suitable for applications that need to withstand pressure and weight. Solubility: At room temperature, aluminum oxide is insoluble in water, which makes it stable in aqueous solutions and does not react with water. ‌

 

Conductivity: Although it is non-conductive at room temperature, aluminum oxide can exhibit certain conductivity under certain conditions, which makes it useful in some electronic and electrical applications. ‌

 

Crystal type: Aluminum oxide is an ionic crystal, which means it has a certain ionic bonding structure and has good hardness and stability. ‌

 

In addition, aluminum oxide has many variants, the most common of which are α-type and γ-type. α-type aluminum oxide (corundum) has a high melting point, high hardness, good corrosion resistance and insulation, while γ-type aluminum oxide has strong water absorption and catalytic activity. ‌These properties make aluminum oxide
