X-ray powder diffraction intensities of (00l) reflections of the orthorhombic 1-2-3 phase are found to depend strongly on the preparation conditions, particularly the calcination temperature of the raw materials. Calcination temperatures above around 925°C cause formation of relatively large crystals of the 1-2-3 phase which retain their morphology even after subsequent sintering. Grinding of these coarse grained specimens leads to relatively more flaky particles due to cleavage fracture along (00l) planes resulting in a strong orientation effect particularly during X-ray powder diffractometry.
