info about zirconium oxide crucibles

The unstable building material ZrO₂ can be removed by adding various oxides like Y₂O₃, MgO, CaO or Al₂O₃ so can be stabilized, that a high-performance ceramic which possesses unique properties.

GTS is increasingly producing parts for laboratory use in the form of crucibles, annealing dishes, tubes, plates and so on... But also special designs for mechanical engineering, Electronics, optics and medical technology are on the advance.

Special properties:

Zirconium oxide is a semiconductor
high mechanical strength
very good wear resistance
high fracture toughness
high temperature resistance up to over 2000°C
low thermal conductivity
high corrosion resistance
