Modern materials
We produce tehnical and industrial ceramics from very high quality materials:
- Aluminium oxide Al203 ceramics according to DIN EN 60672-3 standard.
- Zirconium oxide ceramic ZrO2
- - stabilisied with magnesium ZrO2+MgO
- - stabilised with ytrium ZrO2+Y2O3
- Composite ceramics Al203+ZrO2
- Composite ceramics Al2TiO5 (Al203+TiO2) (Aluminium Titanate)
Due to our technology for production (isostatic press, mechanic press, extruding, injection moulding or casting) we developed wide range of various ceramic products that are used in different industry branches.
Product features
High resistance on abrasion
Resistance on high temperature
High hardness
Resistance on chemicals (base, acids...)
Good electro-isolation characteristics
Low electrical conductivity
