This chart is intended to illustrate typical properties of advanced ceramic materials available from CoorsTek. All data measurements are typical and made at room temperature unless otherwise noted. The designer should recognize that exact properties may vary according to product configuration and close control of values of most properties can be maintained if specified. All CoorsTek ceramic compositions are controlled using modern chemical spectrographic and x-ray fluorescent methods.
