Alumina industrial ceramics‍ material has been seen a lot, this kind of industrial ceramic material application of alumina chemical properties, but not alumina and ceramic combination, this kind of alumina ceramic material and other different materials with the same route, thermal conductivity and ductility have a great advantage.Alumina is also the chemical name of aluminum oxide (Al2O3), while the chemical composition of ceramics are usually silicon dioxide (SiO2) and calcium carbonate (CaCO3).The finishing process of alumina ceramics is powder preparation, this preparation method has high molding rate, fast working efficiency and high success rate of products.

In today's competitive industrial landscape, having access to exceptional products that deliver exceptional performance is paramount. The Alumina Ceramic we offer are precisely what you need to take your industrial applications to new heights. Their unbeatable strength, durability, and unique characteristics make them stand out among other materials, making them an excellent investment for customers.

With the continuous development and progress of science and technology, alumina ceramics have been widely used in various fields, many consumers will ask whether alumina ceramics wear resistance?The following by the cloud star industrial ceramic manufacturers to explain whether alumina ceramics really wear resistance.

Alumina ceramics are widely used in the field of lithium battery membrane coating and catalyst carrier because of their excellent physical and chemical properties.

Medical.Alumina is more used to make artificial bones, artificial joints, artificial teeth and so on.Alumina ceramics have excellent biocompatibility, biological inertia, physical and chemical stability, high hardness and wear resistance, and are ideal materials for the preparation of artificial bones and joints.​

High mechanical strength, the flexural strength of alumina ceramic sintered products can reach 250MPa, hot pressing products can reach 500MPa, the strength can be maintained to 900℃ at high temperature

The Spring Festival holiday is over and the factory is back to normal work.

The Rockwell hardness of alumina ceramics‍ is HRA80-90. The hardness of alumina ceramics is second only to that of diamond, which far exceeds the wear resistance of wear-resistant steel and stainless steel.

Alumina ceramicsare divided into two types: high-purity and ordinary.

After the powder is formed, a biscuit with good shape is obtained, and then the biscuit is heated at a certain temperature. The biscuit undergoes volume shrinkage and finally becomes a compact sintered body. This process is called sintering. The driving force of alumina ceramic green body sintering is mainly the change of powder surface energy, that is, the surface energy of powder decreases, the surface area decreases, and the ceramic densifies. In the process of ceramic sintering densification, material transfer can be carried out through solid phase diffusion, including surface diffusion, grain boundary diffusion, lattice diffusion, etc. Normal pressure sintering is generally used in industry.
