Alumina Ceramic Plates (Al203)

Alumina Plates

Alumina ceramics are the superior ceramic materials made up primarily of aluminum and oxygen. They are well known for being among the finest and most used ceramic materials for plates in many industries. Many manufacturers prefer alumina ceramic plates for several reasons, including excellent heat conductivity, insulating capabilities, corrosion resistance, high melting point, and extreme hardness.

We'll go through the qualities, manufacture, applications of alumina ceramics plates, and any other pertinent facts concerning the material. So let's get started right away!

Applications of LSP Alumina Ceramic Plates

Because of its versatility and inexpensive material cost, alumina (Al2O3) has widespread applications.

  • Alumina ceramic is particularly hard when compared to metals which makes it ideal for equipment used for grinding complex objects such as mortars and pestles and armor for vehicles and personnel.
  • Their ability to withstand erosion and weathering makes them suitable for the chemical industry.
  • They are considered very useful in traditional industries as injector tubes, insulators, and gas nozzles can be made out of them.
  • Because of their capacity to maintain their firmness at extreme temperatures, Alumina tubes are used to make d-furnaces and thermocouple protectors.
  • Alumina materials with high purity are ideal for ion implantation, optical lithography, CVD, and semiconductor components.
  •  With an alumina content higher than 95%, alumina ceramics can be used as excellent electrical insulators. They also have a low dielectric loss, with a wide range of applications in electronics and electrical appliances.
  • Transparent alumina ceramic plates are used to make high-pressure sodium lamps and infrared detecting window material because they have good permeability to visible light and infrared radiation.
  • Other essential applications of alumina ceramic plates can be seen in seal rings, medical prostheses, electronic substrates, ballistic missiles, and batteries.
