Zirconia (ZR-G)

ZrO2 ca.- 8% Y2O3-stab

The unsta­ble build­ing mate­r­ial ZrO2 can be stabilised by adding vari­ous oxides, such as Y2O3, MgO, CaO or Al2O3 , to produce a high-perfor­mance ceramic with unique prop­er­ties. GTS is produc­ing an increas­ing number of parts for labo­ra­tory use in the form of crucibles, anneal­ing dishes, tubes, plates, etc. Besides these, special designs for mechan­i­cal engi­neer­ing, elec­tron­ics, optics and medical tech­nol­ogy are also seeing increas­ing demand.


  • zirco­nia is a semi­con­duc­tor
