In a broad sense, many people consider alumina as a general term for aluminum oxides, aluminum hydroxides, and the like, which are a class of compounds composed of aluminum, oxygen, and hydrogen.

With the development of electronic devices towards miniaturization and high performance, efficient heat dissipation has become a key factor in ensuring the stable operation of devices.

Ceramics used as biomaterials to fill defects in teeth and bones, fix bone grafts, fractures or prostheses to bones, and replace diseased tissues are called bioceramics.

A ceramic filling pump is a precision fluid conveying device with high-performance ceramic materials (such as zirconia and alumina) as its core components.

High-performance ceramic coatings are a general term for a class of non-metallic inorganic coatings that emerged after organic resins, metals, and alloys.

In an era where semiconductor technology is moving towards processes below 3nm, alumina ceramics (Al₂O₃ ceramics) have emerged as a key material supporting the precise operation of semiconductor equipment, thanks to their high purity, excellent insulation, high-temperature resistance, and chemical stability.

Alumina ceramic components, with their excellent properties such as high hardness, high temperature resistance, corrosion resistance, and good insulation, are widely used in electronics, medical, aerospace and other fields.

As one of the most widely used advanced ceramic materials in the industrial field, the performance optimization of alumina ceramics has always been a core topic in scientific research and industry.

Industrial ceramics, especially alumina ceramics, have become the "hidden champions" in the field of high-end manufacturing due to their excellent hardness, wear resistance, and high-temperature resistance.

As a high-performance ceramic material primarily composed of alumina(＞99.3%), corundum tubes have witnessed a surge in demand across advanced industries such as semiconductors, aerospace, and new energy, owing to their exceptional properties including high-temperature resistance, corrosion resistance, and superior hardness.
