TECHNICAL CERAMIC MATERIALS

Engineering ceramics can be made from a variety of materials depending on the desired properties and applications. Some of the most common materials are:

  1. Alumina (Al2O3): This is the most commonly used material for technical ceramics. It has high strength, hardness, rigidity and chemical resistance. It is often used for applications in the electronics, mechanical and chemical industries.

  2. Silicon Carbide (SiC): This material has high strength, hardness and resistance to high temperatures and chemicals. It is often used for applications in the automotive, aerospace and energy industries.

  3. Silicon nitride ceramic (Si3N4) is a material from the group of technical ceramics. It is characterized by high strength, hardness, fracture toughness and temperature resistance. In addition, Si3N4 has good corrosion resistance, electrical insulation properties and low density.

  4. Aluminum nitride (AlN): This material has high thermal conductivity, electrical insulation ability and resistance to high temperatures. It is often used for applications in the electronics and automotive industries.

  5. Titanium oxide (TiO2): This material has a high level of transparency, high resistance to chemicals and weathering, as well as high hardness and scratch resistance. It is often used for applications in the optical industry and coating technology.

  6. MACOR is a special type of glass ceramic, also known as machinable glass ceramic. It is a material characterized by its excellent machinability and high chemical resistance.

There are many other materials that can be used to manufacture technical ceramics. The choice of material depends on the specific requirements of the application, including the required mechanical, thermal, electrical and chemical properties.

Al2O3_Kornstruktur

Aluminum oxide is the most commonly used ceramic material. Thanks to its very good electrical insulation, dielectric strength and high temperature resistance up to 1750°C, it is ideal for electrical applications and high-temperature applications.

THE ADVANTAGES OF ALUMINUM OXIDE CERAMIC

  • High strength

  • High hardness

  • Good temperature resistance

  • High wear resistance

  • High corrosion resistance up to high temperature ranges

  • High biocompatibility 

  • Excellent tribological properties

Zirconium oxide is the high-performance material among the oxide ceramics. It features exceptional fracture toughness, high wear and corrosion resistance, and low thermal conductivity.

THE ADVANTAGES OF ZIRCONIA CERAMIC

  • Very high fracture toughness

  • Very high bending and tensile strength

  • High wear resistance

  • High compressive strength

  • Very low thermal conductivity

  • Thermal expansion similar to cast iron

  • Modulus of elasticity comparable to steel

  • oxygen ion conductivity

  • Very good tribological properties

  • Excellent surface finish and sharp edges possible

The optimal properties of both materials are realized in our mixed oxide ceramics .

 

-Main component ZrO2 is called ATZ (Alumina Toughened Zirconia)

-Main component Al2O3 hot ZTA (Zirconia Toughened Alumina) 

THE ADVANTAGES OF MIXED OXIDE CERAMICS

The background of the mixtures is to combine the "good" properties of both oxides:

The great strength and toughness of zirconia with the hardness and wear resistance of alumina.

With a suitable proportion of ZrO2  in the ZTA material, the high electrical insulation of the Al2O3  is retained.
