Wide application range
Polishing
High purity aluminum oxide powder used for precision polishing has low impurity content, small particle size, high polishing efficiency, and high polishing glossiness. It is widely used in the precision polishing industry and can meet the precision polishing requirements of products with low impurity content. Suitable for precision polishing of materials such as sapphire, glass, metal, semiconductor, plastic, etc., making their surfaces less prone to defects.
Ceramic industry
Aluminum oxide can be widely used in the production of ceramics. Aluminum oxide ceramics have many excellent properties, such as high mechanical strength, high insulation, high hardness, wear resistance, corrosion resistance, and high temperature resistance; Aluminum oxide can also be used as electronic ceramics, such as vacuum devices, circuit substrates, spark plug insulation ceramics, etc. In addition, alumina is also widely used in structural ceramics, chemical ceramic materials, and fine ceramics.
Refractory materials
When alumina is used for refractory materials, it is mainly used for producing refractory boards, refractory bricks, insulation and other refractory materials. Refractory materials are stacked inside the shell of the smelting furnace, playing a role in insulation and heat preservation. At the same time, it also protects the outer shell of the smelting furnace from being melted by the high temperature inside the furnace. Refractory bricks are mainly used in the metallurgical industry, such as in the construction of steel kilns.
The electronics industry
Aluminum oxide has a wide range of applications in the electronics industry, mainly as a basic material for electronic components. Due to its excellent insulation performance, high thermal conductivity, and conductivity, it can be used to manufacture capacitors, resistors, transistors, integrated circuits, and semiconductor devices. Aluminum oxide can also be used as a heat sink and packaging material for electronic devices, ensuring their normal operation.
Lithium battery diaphragm
High purity nano alumina is used as a ceramic coating between the positive and negative electrodes of lithium batteries, which has good heat resistance, high temperature resistance, and insulation performance, avoiding melting of the battery at high temperatures and causing short circuits.
Used as a catalyst and catalyst carrier
Aluminum oxide, as a catalyst and catalyst carrier, is widely used in the fields of petrochemicals, chemical reagents, food processing, etc. It can be used to prepare various chemical products such as acids, bases, ammonium, phosphates, etc. In agriculture, it can be used as an antibacterial agent, herbicide, and plant growth regulator. Therefore, alumina can be used to prepare various chemical products and has important catalytic effects.
Artificial gemstone
Aluminum oxide is widely used in the production of ruby and sapphire. In the process of making ruby and sapphire, alumina, as a high-temperature resistant material, can help us produce high hardness and high-temperature resistant ruby and sapphire. In addition, the corrosion resistance of alumina also makes the production of ruby and sapphire more reliable. Therefore, alumina plays an important role in the production of ruby and sapphire.
