TECHNICAL CERAMICS MATERIALS

Technical ceramics is the umbrella term for ceramic materials which, depending on the requirement profile, have very different properties / properties.

Download the technical ceramic material table and look at the material specifications in detail and compare them with each other.

ALUMINUM OXIDE / AL2O3

96% - 99.7% - 99.9%

Aluminum oxide is the most frequently 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 CERAMICS

 

  • High strength

  • High hardness

  • Good temperature resistance

  • High wear resistance

  • High corrosion resistance up to high temperature ranges

  • High biocompatibility

  • Excellent tribological properties

ZIRCONIA / ZRO2

3Y-TZP - MG-PSZ

Zirconium oxide is the high-performance material among oxide ceramics. It is characterized by exceptional fracture toughness, high wear resistance and corrosion resistance as well as a 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 that of cast iron

  • E-module comparable to steel

  • Oxygen ion conductivity

  • Very good tribological properties

  • Excellent surface quality and sharp edges possible

MIXED OXIDS / ATZ - ZTA

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 are called 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 zirconium oxide with the hardness and wear resistance of aluminum oxide.

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

SILICON CARBIDE / SIC

Light and yet extremely stable - that's what distinguishes silicon carbide. Also known as silicon carbide or silicon carbide, the ceramic material shows excellent properties for a wide range of applications. Silicon carbide components are ideal for applications in which wear resistance, high rigidity, corrosion and temperature resistance are essential.

THE ADVANTAGES OF SILICON CARBIDE

 

  • Excellent chemical resistance

  • High strength

  • Excellent corrosion resistance even at very high application temperatures

  • Excellent mechanical high temperature properties

  • Good thermal shock resistance

  • Low thermal expansion

  • Very high thermal conductivity

  • High wear resistance

  • Very high rigidity

SILICON NITRIDE / SI3N4

The ceramic material silicon nitride (also: silicon nitride) is the all-round talent among technical ceramics. With its high strength and fracture toughness, very good thermal shock resistance as well as its excellent wear and impact resistance, silicon nitride is suitable for a wide variety of applications.

THE ADVANTAGES OF SILICON NITRIDE CERAMICS

 

  • Very good strength up to high temperature ranges (> 1200 ° C)

  • Excellent wear and impact resistance

  • High hardness

  • Fracture toughness

  • Low thermal expansion

  • Relatively low thermal conductivity

  • Very good thermal shock resistance

  • Very good chemical resistance

  • Electrically conductive material available

MACOR® / GLASS CERAMICS

It combines the performance of a technical ceramic with the versatility of a high-performance plastic - making it an outstandingly machinable material. By turning and milling, even the most demanding fittings and the smallest precision parts can be manufactured. If the performance of a technical ceramic is required and the application requires the production of a complicated shape, Macor® glass ceramic is the ideal material. It helps to significantly reduce the time between development and application and thereby reduce costs.

THE ADVANTAGES OF MACOR ® / GLASS CERAMICS

 

  • Cost effective in processing

  • Most complex shapes possible

  • Radiation resistant

  • Low thermal conductivity

  • Very high service temperature

  • Good electrical insulator

  • No porosity and no outgassing

  • Short lead times

  • No smooth fire required
