zirconia ceramic
Zirconia/ZrO2/ Zirconium is famous of its extremely density, extraodinary mechanical strength, wear and abrasive resistance, high toughness and low thermal conductivity and thermal expansion coefficient. We offer a selection of different grade material for producing zirconia ceramic tube, the typical one include yittria partial stabilized, magnesia stabilized zirconia. We are capable of producing variety of zirconia ceramic rod from small size to large size.
