Abstract： |
A RE zirconate coating material for preparing high-temp heat barrier layer has a chemical formula: A2B2O7, where A is chosen from La, Nd, Sm, Gd, Dy, Er and Yb and B is Zr. It is prepared through ball grinding of raw materials, baking, die pressing, and reaction in air at 1550-1650 deg.C. It has low heat conductivity and high high-temp stability. |
