Ceramic materials with low thermal conductivity and low coefficients of thermal expansion

Patent Brown, Jesse ; Hirschfeld, Deidre ; Liu, Dean-Mo ; Yang, Yaping ; Li, Tingkai ; Swanson, Robert E. ; Van Aken, Steven ; Kim, Jin-Min

Compositions having the general formula (Ca.sub.x Mg.sub.1-x)Zr.sub.4 (PO.sub.4).sub.6 where x is between 0.5 and 0.99 are produced by solid state and sol-gel processes. In a preferred embodiment, when x is between 0.5 and 0.8, the MgCZP materials have near-zero coefficients of thermal expansion. The MgCZPs of the present invention also show unusually low thermal conductivities, and are stable at high temperatures. Macrostructures formed from MgCZP are useful in a wide variety of high-temperature applications. In a preferred process, calcium, magnesium, and zirconium nitrate solutions have their pH adjusted to between 7 and 9 either before or after the addition ofmore »« less
