Ceramics are materials 2700 – 2850 0.7 5.1 25 20 no no not known stabilised prepared by the action of heat zirconia followed by cooling. This ceramic includes zirconia (ZrO2) and yttria (Y2O3). Thermal conductivity is a measure of how well a material conducts heat. The bigger the value, the better it conducts. Tensile strength is a measure of the strength of a material when subjected to pulling forces. The bigger the value, the stronger the material. Stiffness is given by Young’s modulus. The bigger the value, the stiffer (and less flexible) the material. If a material corrodes it reacts slowly with oxygen or water from the air, and is damaged over time. The rusting of iron is an example of corrosion.
