ZnO solidus and liquidus boundaries in the ZnO‐Bi 2 O 3 system were investigated via analytical electron microscopy (AEM), electron probe microanalysis (EPMA), and secondary ion mass spectrometry (SIMS). The Bi 2 O 3 solubility is highest—0.24 ± 0.04 mol%—at the eutectic temperature of 740°C and decreases rapidly with increasing temperature. Detection limits and quantification procedures of X‐ray microanalysis (AEM, EPMA) and ion microanalysis (SIMS) are discussed with respect to the determination of phase diagrams involving low solubility phases.
