95% ZrO2 Zirconia (YSZ) Rod
Product Overview
Yttria stabilized zirconia(YTZP) is a sintered advanced ceramic material and it is the most common form of stabilized zirconia ceramic. Typical composition of Yttria Stabilized Zirconia is 94.7% ZrO2 + 5.2% Y2O3(weight percentage) or 97 ZrO2 + 3% Y2O3 (mol percentage)
Compared with alumina rod Yttria stabilized zirconia (YSZ YTZP) rods could withstand even higher temperature. Zirconia also has better corrosion and wearing resistance. As an extremely refractory material, working temperature of zirconia rods could be as high as 1900C and being stable to most of corrosive chemicals as well. Zirconia crucibles also provide very low thermal and electrical conductivity amking it an ideal for applications requires electrical and thermal insulating
However, unlike boron nitride, Zirconia rod is not recommended to be used as a raw material for further machining work, due to the high hardness and wearing resistance.
