Yttria Stabilized Zirconia Ceramic Rod

Yttria Stabilized Zirconia Ceramic Rod

1. Zirconia ceramic rod  has the highest strength and toughness at room temperature of all the advanced ceramic materials. The fine grain size allows for extremely smooth surfaces and sharp edges.

2. Excellent thermal insulation/low thermal conductivity (2.5 to 3 W/mK),

3. Very high resistance to crack propagation, high fracture toughness (6.5 to 8 MPam1/2).

Zirconia Ceramic Rod is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.
