TECHNICAL CERAMICS
TECHNOLOGY APPLIED TO THE TECHNICAL CERAMICS
Our materials are outstanding for their extreme hardness and non-wearing capacity, low electrical and thermal conductivity, chemical resistance, resistance to abrasive materials, and for their high biocompatibility.
Zirconia Steelceram
Zirconia is a technical ceramic with a unique crystalline structure that is extremely resistant. This structure allows it to prevent the propagation of cracks through the core, providing excellent mechanical resistance and extreme hardness. As most other ceramics, it does not conduct electricity, and the maximum operating temperature is also very high.

SPECIFICATIONS OF OUR TECHNICAL CERAMICS
The specific characteristics of each technical ceramic make this material appropriate for a specific application in different industrial environments. All technical ceramics have high hardness and consequently high wear resistance.
HIGH TEMPERATURE
Technical ceramics resist high temperatures and thermal shock very well, they are used in applications submitted to 1000ºC in which most of the materials melt.
CHEMICAL RESISTANCE
Thanks to the chemical resistance of the material, it is used in applications in contact with abrasive chemicals such as those in agriculture or pharmaceuticals.
BENDING STRENGTH
Technical ceramics have good bending strength, so they do not break easily.
COMPRESSIVE STRENGTH
Technical ceramics have excellent compressive strength, which means that they are able to stand high crushing loads.
DIELECTRICITY
Ceramic materials are not usually electro conductive having a low coefficient of thermal conductivity, which makes them optimum materials for welding processes or high temperature applications such as high-performance engines.
BIOCOMPATIBILITY
Technical ceramics do not react chemically to external agents, making them a suitable material for medical applications such as prosthetics or dental implants.
IMPACT RESISTANCE
While most ceramics are more fragile, some of the technical ceramics offer a good resistance to impact by resisting shocks properly.
CORROSION RESISTANCE
In comparison to many other metals, the technical ceramics do not suffer by corrosion when they enter in contact with air and water.
