| Zirconia materials feature the lowest thermal conductivity of structural-grade ceramics. The thermal expansion of zirconia is similar to cast iron, which helps minimize stresses in ceramic-metal assemblies. Dura-Z is a transformation-toughened zirconia offering superior strength, toughness, wear, and corrosion resistance. Transformation toughening imparts impact resistance and durability in cyclic fatigue environments. Dura-Z is recommended for valve and pump components, bushings and wear sleeves, oil and gas down-hole tools, and industrial tooling applications. Thermal Shock Delta Tc = 350°C - Thermal shock tests are performed by quenching samples in water from different elevated temperatures. Delta Tc is the change in temperature which results in a sharp decrease in the flexural strength of the sample. Data Provided by the manufacturer, CoorsTek, Inc. |
