| description | The present invention relates to a ceramic heat exchanger manufactured from an oxide material that is highly refractory and highly stable in a wide range of oxygen partial pressures and in the presence of certain gases and which is capable of operating at temperatures ranging from below 400 to well above 1300° C. for a prolonged period of time. The oxide material is represented by the formula: A1-xBxO(3+x+z)/2 where A is selected from the group consisting of La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, and mixtures thereof, B represents Zr, Ti or Hf or mixtures thereof, x is greater than or equal to zero and less than or equal to one, and z is a number that renders the compound charge neutral and is greater than about -0.1 and less than about 0.2. |
