A novel solid solution has a composition of R y Zr₄Si x P 6-x O₂₄ (R is at least one element capable of forming bivalent or trivalent cation, 0≦x≦2, 2/3≦y≦2). Furthermore, heat-resistant sintered body and heat-resistant phosphate based compound sintered body comprises the above solid solution and has excellent heat resistance and high temperature stability. And also, a method of producing such sintered bodies is disclosed. |
