| Abstract: | We have used the electron spin resonance of Mn2+ ions to study the zirconia-calcia system from 9 to 60 mole% CaO. With the exception of single crystals of calcia-stabilized zirconia (CSZ) with 15 and 20 mole% CaO, the experiments were carried out on polycrystalline samples. From the different values measured for the hyperfine coupling constant A with increasing amount of calcia, we have deduced that Mn2+ substitutes for Ca2+ in the three following host lattices: cubic CSZ, CaZrO3, and CaO. |
